+High Performance, Feature-Rich Idiomatic Go codec/encoding library for 
+binc, msgpack, cbor, json.
+
+Supported Serialization formats are:
+
+  - msgpack: https://github.com/msgpack/msgpack
+  - binc:    http://github.com/ugorji/binc
+  - cbor:    http://cbor.io http://tools.ietf.org/html/rfc7049
+  - json:    http://json.org http://tools.ietf.org/html/rfc7159
+  - simple: 
+
+To install:
+
+    go get github.com/ugorji/go/codec
+
+This package understands the 'unsafe' tag, to allow using unsafe semantics:
+
+  - When decoding into a struct, you need to read the field name as a string 
+    so you can find the struct field it is mapped to.
+    Using `unsafe` will bypass the allocation and copying overhead of []byte->string conversion.
+
+To install using unsafe, pass the 'unsafe' tag:
+
+    go get -tags=unsafe github.com/ugorji/go/codec
+
+For detailed usage information, read the primer at http://ugorji.net/blog/go-codec-primer .
+
+The idiomatic Go support is as seen in other encoding packages in
+the standard library (ie json, xml, gob, etc).
+
+Rich Feature Set includes:
+
+  - Simple but extremely powerful and feature-rich API
+  - Very High Performance.
+    Our extensive benchmarks show us outperforming Gob, Json, Bson, etc by 2-4X.
+  - Multiple conversions:
+    Package coerces types where appropriate 
+    e.g. decode an int in the stream into a float, etc.
+  - Corner Cases: 
+    Overflows, nil maps/slices, nil values in streams are handled correctly
+  - Standard field renaming via tags
+  - Support for omitting empty fields during an encoding
+  - Encoding from any value and decoding into pointer to any value
+    (struct, slice, map, primitives, pointers, interface{}, etc)
+  - Extensions to support efficient encoding/decoding of any named types
+  - Support encoding.(Binary|Text)(M|Unm)arshaler interfaces
+  - Decoding without a schema (into a interface{}).
+    Includes Options to configure what specific map or slice type to use
+    when decoding an encoded list or map into a nil interface{}
+  - Encode a struct as an array, and decode struct from an array in the data stream
+  - Comprehensive support for anonymous fields
+  - Fast (no-reflection) encoding/decoding of common maps and slices
+  - Code-generation for faster performance.
+  - Support binary (e.g. messagepack, cbor) and text (e.g. json) formats
+  - Support indefinite-length formats to enable true streaming 
+    (for formats which support it e.g. json, cbor)
+  - Support canonical encoding, where a value is ALWAYS encoded as same sequence of bytes.
+    This mostly applies to maps, where iteration order is non-deterministic.
+  - NIL in data stream decoded as zero value
+  - Never silently skip data when decoding.
+    User decides whether to return an error or silently skip data when keys or indexes
+    in the data stream do not map to fields in the struct.
+  - Detect and error when encoding a cyclic reference (instead of stack overflow shutdown)
+  - Encode/Decode from/to chan types (for iterative streaming support)
+  - Drop-in replacement for encoding/json. `json:` key in struct tag supported.
+  - Provides a RPC Server and Client Codec for net/rpc communication protocol.
+  - Handle unique idiosyncrasies of codecs e.g. 
+    - For messagepack, configure how ambiguities in handling raw bytes are resolved 
+    - For messagepack, provide rpc server/client codec to support 
+      msgpack-rpc protocol defined at:
+      https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md
+  
+Extension Support
+
+Users can register a function to handle the encoding or decoding of
+their custom types.
+
+There are no restrictions on what the custom type can be. Some examples:
+
+    type BisSet   []int
+    type BitSet64 uint64
+    type UUID     string
+    type MyStructWithUnexportedFields struct { a int; b bool; c []int; }
+    type GifImage struct { ... }
+
+As an illustration, MyStructWithUnexportedFields would normally be
+encoded as an empty map because it has no exported fields, while UUID
+would be encoded as a string. However, with extension support, you can
+encode any of these however you like.
+
+RPC
+
+RPC Client and Server Codecs are implemented, so the codecs can be used
+with the standard net/rpc package.
+
+Usage
+
+The Handle is SAFE for concurrent READ, but NOT SAFE for concurrent modification.
+
+The Encoder and Decoder are NOT safe for concurrent use.
+
+Consequently, the usage model is basically:
+
+    - Create and initialize the Handle before any use.
+      Once created, DO NOT modify it.
+    - Multiple Encoders or Decoders can now use the Handle concurrently.
+      They only read information off the Handle (never write).
+    - However, each Encoder or Decoder MUST not be used concurrently
+    - To re-use an Encoder/Decoder, call Reset(...) on it first.
+      This allows you use state maintained on the Encoder/Decoder.
+
+Sample usage model:
+
+    // create and configure Handle
+    var (
+      bh codec.BincHandle
+      mh codec.MsgpackHandle
+      ch codec.CborHandle
+    )
+
+    mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
+
+    // configure extensions
+    // e.g. for msgpack, define functions and enable Time support for tag 1
+    // mh.SetExt(reflect.TypeOf(time.Time{}), 1, myExt)
+
+    // create and use decoder/encoder
+    var (
+      r io.Reader
+      w io.Writer
+      b []byte
+      h = &bh // or mh to use msgpack
+    )
+
+    dec = codec.NewDecoder(r, h)
+    dec = codec.NewDecoderBytes(b, h)
+    err = dec.Decode(&v)
+
+    enc = codec.NewEncoder(w, h)
+    enc = codec.NewEncoderBytes(&b, h)
+    err = enc.Encode(v)
+
+    //RPC Server
+    go func() {
+        for {
+            conn, err := listener.Accept()
+            rpcCodec := codec.GoRpc.ServerCodec(conn, h)

+// Benefits of go-codec:
+//
+//    - encoding/json always reads whole file into memory first.
+//      This makes it unsuitable for parsing very large files.
+//    - encoding/xml cannot parse into a map[string]interface{}
+//      I found this out on reading https://github.com/clbanning/mxj
+
+// TODO:
+//
+//   - optimization for codecgen:
+//     if len of entity is <= 3 words, then support a value receiver for encode.
+//   - (En|De)coder should store an error when it occurs.
+//     Until reset, subsequent calls return that error that was stored.
+//     This means that free panics must go away.
+//     All errors must be raised through errorf method.
+//   - Decoding using a chan is good, but incurs concurrency costs.
+//     This is because there's no fast way to use a channel without it
+//     having to switch goroutines constantly.
+//     Callback pattern is still the best. Maybe consider supporting something like:
+//        type X struct {
+//             Name string
+//             Ys []Y
+//             Ys chan <- Y
+//             Ys func(Y) -> call this function for each entry
+//        }
+//    - Consider adding a isZeroer interface { isZero() bool }
+//      It is used within isEmpty, for omitEmpty support.
+//    - Consider making Handle used AS-IS within the encoding/decoding session.
+//      This means that we don't cache Handle information within the (En|De)coder,
+//      except we really need it at Reset(...)
+//    - Consider adding math/big support
+//    - Consider reducing the size of the generated functions:
+//      Maybe use one loop, and put the conditionals in the loop.
+//      for ... { if cLen > 0 { if j == cLen { break } } else if dd.CheckBreak() { break } }

+# Codec
+
+High Performance, Feature-Rich Idiomatic Go codec/encoding library for
+binc, msgpack, cbor, json.
+
+Supported Serialization formats are:
+
+  - msgpack: https://github.com/msgpack/msgpack
+  - binc:    http://github.com/ugorji/binc
+  - cbor:    http://cbor.io http://tools.ietf.org/html/rfc7049
+  - json:    http://json.org http://tools.ietf.org/html/rfc7159
+  - simple: 
+
+To install:
+
+    go get github.com/ugorji/go/codec
+
+This package understands the `unsafe` tag, to allow using unsafe semantics:
+
+  - When decoding into a struct, you need to read the field name as a string 
+    so you can find the struct field it is mapped to.
+    Using `unsafe` will bypass the allocation and copying overhead of `[]byte->string` conversion.
+
+To use it, you must pass the `unsafe` tag during install:
+
+```
+go install -tags=unsafe github.com/ugorji/go/codec 
+```
+
+Online documentation: http://godoc.org/github.com/ugorji/go/codec  
+Detailed Usage/How-to Primer: http://ugorji.net/blog/go-codec-primer
+
+The idiomatic Go support is as seen in other encoding packages in
+the standard library (ie json, xml, gob, etc).
+
+Rich Feature Set includes:
+
+  - Simple but extremely powerful and feature-rich API
+  - Very High Performance.
+    Our extensive benchmarks show us outperforming Gob, Json, Bson, etc by 2-4X.
+  - Multiple conversions:
+    Package coerces types where appropriate 
+    e.g. decode an int in the stream into a float, etc.
+  - Corner Cases: 
+    Overflows, nil maps/slices, nil values in streams are handled correctly
+  - Standard field renaming via tags
+  - Support for omitting empty fields during an encoding
+  - Encoding from any value and decoding into pointer to any value
+    (struct, slice, map, primitives, pointers, interface{}, etc)
+  - Extensions to support efficient encoding/decoding of any named types
+  - Support encoding.(Binary|Text)(M|Unm)arshaler interfaces
+  - Decoding without a schema (into a interface{}).
+    Includes Options to configure what specific map or slice type to use
+    when decoding an encoded list or map into a nil interface{}
+  - Encode a struct as an array, and decode struct from an array in the data stream
+  - Comprehensive support for anonymous fields
+  - Fast (no-reflection) encoding/decoding of common maps and slices
+  - Code-generation for faster performance.
+  - Support binary (e.g. messagepack, cbor) and text (e.g. json) formats
+  - Support indefinite-length formats to enable true streaming 
+    (for formats which support it e.g. json, cbor)
+  - Support canonical encoding, where a value is ALWAYS encoded as same sequence of bytes.
+    This mostly applies to maps, where iteration order is non-deterministic.
+  - NIL in data stream decoded as zero value
+  - Never silently skip data when decoding.
+    User decides whether to return an error or silently skip data when keys or indexes
+    in the data stream do not map to fields in the struct.
+  - Encode/Decode from/to chan types (for iterative streaming support)
+  - Drop-in replacement for encoding/json. `json:` key in struct tag supported.
+  - Provides a RPC Server and Client Codec for net/rpc communication protocol.
+  - Handle unique idiosyncrasies of codecs e.g. 
+    - For messagepack, configure how ambiguities in handling raw bytes are resolved 
+    - For messagepack, provide rpc server/client codec to support
+      msgpack-rpc protocol defined at:
+      https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md
+
+## Extension Support
+
+Users can register a function to handle the encoding or decoding of
+their custom types.
+
+There are no restrictions on what the custom type can be. Some examples:
+
+    type BisSet   []int
+    type BitSet64 uint64
+    type UUID     string
+    type MyStructWithUnexportedFields struct { a int; b bool; c []int; }
+    type GifImage struct { ... }
+
+As an illustration, MyStructWithUnexportedFields would normally be
+encoded as an empty map because it has no exported fields, while UUID
+would be encoded as a string. However, with extension support, you can
+encode any of these however you like.
+
+## RPC
+
+RPC Client and Server Codecs are implemented, so the codecs can be used
+with the standard net/rpc package.
+
+## Usage
+
+Typical usage model:
+
+    // create and configure Handle
+    var (
+      bh codec.BincHandle
+      mh codec.MsgpackHandle
+      ch codec.CborHandle
+    )
+
+    mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
+
+    // configure extensions
+    // e.g. for msgpack, define functions and enable Time support for tag 1
+    // mh.SetExt(reflect.TypeOf(time.Time{}), 1, myExt)
+
+    // create and use decoder/encoder
+    var (
+      r io.Reader
+      w io.Writer
+      b []byte
+      h = &bh // or mh to use msgpack
+    )
+
+    dec = codec.NewDecoder(r, h)
+    dec = codec.NewDecoderBytes(b, h)
+    err = dec.Decode(&v)
+
+    enc = codec.NewEncoder(w, h)
+    enc = codec.NewEncoderBytes(&b, h)
+    err = enc.Encode(v)
+
+    //RPC Server
+    go func() {
+        for {
+            conn, err := listener.Accept()
+            rpcCodec := codec.GoRpc.ServerCodec(conn, h)
+            //OR rpcCodec := codec.MsgpackSpecRpc.ServerCodec(conn, h)
+            rpc.ServeCodec(rpcCodec)
+        }
+    }()
+
+    //RPC Communication (client side)
+    conn, err = net.Dial("tcp", "localhost:5555")
+    rpcCodec := codec.GoRpc.ClientCodec(conn, h)
+    //OR rpcCodec := codec.MsgpackSpecRpc.ClientCodec(conn, h)
+    client := rpc.NewClientWithCodec(rpcCodec)

+
+// CborHandle is a Handle for the CBOR encoding format,
+// defined at http://tools.ietf.org/html/rfc7049 and documented further at http://cbor.io .
+//
+// CBOR is comprehensively supported, including support for:
+//   - indefinite-length arrays/maps/bytes/strings
+//   - (extension) tags in range 0..0xffff (0 .. 65535)
+//   - half, single and double-precision floats
+//   - all numbers (1, 2, 4 and 8-byte signed and unsigned integers)
+//   - nil, true, false, ...
+//   - arrays and maps, bytes and text strings
+//
+// None of the optional extensions (with tags) defined in the spec are supported out-of-the-box.
+// Users can implement them as needed (using SetExt), including spec-documented ones:
+//   - timestamp, BigNum, BigFloat, Decimals, Encoded Text (e.g. URL, regexp, base64, MIME Message), etc.
+//
+// To encode with indefinite lengths (streaming), users will use
+// (Must)Encode methods of *Encoder, along with writing CborStreamXXX constants.
+//
+// For example, to encode "one-byte" as an indefinite length string:
+//     var buf bytes.Buffer
+//     e := NewEncoder(&buf, new(CborHandle))
+//     buf.WriteByte(CborStreamString)
+//     e.MustEncode("one-")
+//     e.MustEncode("byte")
+//     buf.WriteByte(CborStreamBreak)
+//     encodedBytes := buf.Bytes()
+//     var vv interface{}
+//     NewDecoderBytes(buf.Bytes(), new(CborHandle)).MustDecode(&vv)
+//     // Now, vv contains the same string "one-byte"

+// Fast path functions try to create a fast path encode or decode implementation
+// for common maps and slices.
+//
+// We define the functions and register then in this single file
+// so as not to pollute the encode.go and decode.go, and create a dependency in there.
+// This file can be omitted without causing a build failure.
+//
+// The advantage of fast paths is:
+//    - Many calls bypass reflection altogether
+// 
+// Currently support
+//    - slice of all builtin types,
+//    - map of all builtin types to string or interface value
+//    - symmetrical maps of all builtin types (e.g. str-str, uint8-uint8)
+// This should provide adequate "typical" implementations.
+// 
+// Note that fast track decode functions must handle values for which an address cannot be obtained.
+// For example: 
+//   m2 := map[string]int{}
+//   p2 := []interface{}{m2}
+//   // decoding into p2 will bomb if fast track functions do not treat like unaddressable.

+// SimpleHandle is a Handle for a very simple encoding format.
+//
+// simple is a simplistic codec similar to binc, but not as compact.
+//   - Encoding of a value is always preceded by the descriptor byte (bd)
+//   - True, false, nil are encoded fully in 1 byte (the descriptor)
+//   - Integers (intXXX, uintXXX) are encoded in 1, 2, 4 or 8 bytes (plus a descriptor byte).
+//     There are positive (uintXXX and intXXX >= 0) and negative (intXXX < 0) integers.
+//   - Floats are encoded in 4 or 8 bytes (plus a descriptor byte)
+//   - Lenght of containers (strings, bytes, array, map, extensions)
+//     are encoded in 0, 1, 2, 4 or 8 bytes.
+//     Zero-length containers have no length encoded.
+//     For others, the number of bytes is given by pow(2, bd%3)
+//   - maps are encoded as [bd] [length] [[key][value]]...
+//   - arrays are encoded as [bd] [length] [value]...
+//   - extensions are encoded as [bd] [length] [tag] [byte]...
+//   - strings/bytearrays are encoded as [bd] [length] [byte]...
+//
+// The full spec will be published soon.

+//
+// Format Description
+//
+//   A timestamp is composed of 3 components:
+//
+//   - secs: signed integer representing seconds since unix epoch
+//   - nsces: unsigned integer representing fractional seconds as a
+//     nanosecond offset within secs, in the range 0 <= nsecs < 1e9
+//   - tz: signed integer representing timezone offset in minutes east of UTC,
+//     and a dst (daylight savings time) flag
+//
+//   When encoding a timestamp, the first byte is the descriptor, which
+//   defines which components are encoded and how many bytes are used to
+//   encode secs and nsecs components. *If secs/nsecs is 0 or tz is UTC, it
+//   is not encoded in the byte array explicitly*.
+//
+//       Descriptor 8 bits are of the form `A B C DDD EE`:
+//           A:   Is secs component encoded? 1 = true
+//           B:   Is nsecs component encoded? 1 = true
+//           C:   Is tz component encoded? 1 = true
+//           DDD: Number of extra bytes for secs (range 0-7).
+//                If A = 1, secs encoded in DDD+1 bytes.
+//                    If A = 0, secs is not encoded, and is assumed to be 0.
+//                    If A = 1, then we need at least 1 byte to encode secs.
+//                    DDD says the number of extra bytes beyond that 1.
+//                    E.g. if DDD=0, then secs is represented in 1 byte.
+//                         if DDD=2, then secs is represented in 3 bytes.
+//           EE:  Number of extra bytes for nsecs (range 0-3).
+//                If B = 1, nsecs encoded in EE+1 bytes (similar to secs/DDD above)
+//
+//   Following the descriptor bytes, subsequent bytes are:
+//
+//       secs component encoded in `DDD + 1` bytes (if A == 1)
+//       nsecs component encoded in `EE + 1` bytes (if B == 1)
+//       tz component encoded in 2 bytes (if C == 1)
+//
+//   secs and nsecs components are integers encoded in a BigEndian
+//   2-complement encoding format.
+//
+//   tz component is encoded as 2 bytes (16 bits). Most significant bit 15 to
+//   Least significant bit 0 are described below:
+//
+//       Timezone offset has a range of -12:00 to +14:00 (ie -720 to +840 minutes).
+//       Bit 15 = have\_dst: set to 1 if we set the dst flag.
+//       Bit 14 = dst\_on: set to 1 if dst is in effect at the time, or 0 if not.
+//       Bits 13..0 = timezone offset in minutes. It is a signed integer in Big Endian format.

+
+Server-sent events (SSE) is a technology where a browser receives automatic updates from a server via HTTP connection. The Server-Sent Events EventSource API is [standardized as part of HTML5[1] by the W3C](http://www.w3.org/TR/2009/WD-eventsource-20091029/).
+
+- [Read this great SSE introduction by the HTML5Rocks guys](http://www.html5rocks.com/en/tutorials/eventsource/basics/)
+- [Browser support](http://caniuse.com/#feat=eventsource)
+
+## Sample code
+
+```go
+import "github.com/gin-contrib/sse"
+
+func httpHandler(w http.ResponseWriter, req *http.Request) {
+	// data can be a primitive like a string, an integer or a float
+	sse.Encode(w, sse.Event{
+		Event: "message",
+		Data:  "some data\nmore data",
+	})
+
+	// also a complex type, like a map, a struct or a slice
+	sse.Encode(w, sse.Event{
+		Id:    "124",
+		Event: "message",
+		Data: map[string]interface{}{
+			"user":    "manu",
+			"date":    time.Now().Unix(),
+			"content": "hi!",
+		},
+	})
+}
+```
+```
+event: message
+data: some data\\nmore data
+
+id: 124
+event: message
+data: {"content":"hi!","date":1431540810,"user":"manu"}
+ 
+```
+
+## Content-Type
+
+```go
+fmt.Println(sse.ContentType)
+```
+```
+text/event-stream
+```
+
+## Decoding support
+
+There is a client-side implementation of SSE coming soon.
