+ * @template {import("../source/Vector.js").default} VectorSourceType
+ * @typedef {Object} Options
+ * @property {string} [className='ol-layer'] A CSS class name to set to the layer element.
+ * @property {number} [opacity=1] Opacity (0, 1).
+ * @property {boolean} [visible=true] Visibility.
+ * @property {import("../extent.js").Extent} [extent] The bounding extent for layer rendering.  The layer will not be
+ * rendered outside of this extent.
+ * @property {number} [zIndex] The z-index for layer rendering.  At rendering time, the layers
+ * will be ordered, first by Z-index and then by position. When `undefined`, a `zIndex` of 0 is assumed
+ * for layers that are added to the map's `layers` collection, or `Infinity` when the layer's `setMap()`
+ * method was used.
+ * @property {number} [minResolution] The minimum resolution (inclusive) at which this layer will be
+ * visible.
+ * @property {number} [maxResolution] The maximum resolution (exclusive) below which this layer will
+ * be visible.
+ * @property {number} [minZoom] The minimum view zoom level (exclusive) above which this layer will be
+ * visible.
+ * @property {number} [maxZoom] The maximum view zoom level (inclusive) at which this layer will
+ * be visible.
+ * @property {import("../render.js").OrderFunction} [renderOrder] Render order. Function to be used when sorting
+ * features before rendering. By default features are drawn in the order that they are created. Use
+ * `null` to avoid the sort, but get an undefined draw order.
+ * @property {number} [renderBuffer=100] The buffer in pixels around the viewport extent used by the
+ * renderer when getting features from the vector source for the rendering or hit-detection.
+ * Recommended value: the size of the largest symbol, line width or label.
+ * @property {VectorSourceType} [source] Source.
+ * @property {import("../PluggableMap.js").default} [map] Sets the layer as overlay on a map. The map will not manage
+ * this layer in its layers collection, and the layer will be rendered on top. This is useful for
+ * temporary layers. The standard way to add a layer to a map and have it managed by the map is to
+ * use {@link import("../PluggableMap.js").default#addLayer map.addLayer()}.
+ * @property {boolean} [declutter=false] Declutter images and text on this layer. The priority is defined
+ * by the `zIndex` of the style and the render order of features. Higher z-index means higher priority.
+ * Within the same z-index, a feature rendered before another has higher priority.
+ * @property {import("../style/Style.js").StyleLike|null} [style] Layer style. When set to `null`, only
+ * features that have their own style will be rendered. See {@link module:ol/style/Style~Style} for the default style
+ * which will be used if this is not set.
+ * @property {number} [imageRatio=1] Ratio by which the rendered extent should be larger than the
+ * viewport extent. A larger ratio avoids cut images during panning, but will cause a decrease in performance.
+ * @property {Object<string, *>} [properties] Arbitrary observable properties. Can be accessed with `#get()` and `#set()`.

+/**
+ * @classdesc
+ * Vector data is rendered client-side, to an image. This layer type provides great performance
+ * during panning and zooming, but point symbols and texts are always rotated with the view and
+ * pixels are scaled during zoom animations. For more accurate rendering of vector data, use
+ * {@link module:ol/layer/Vector~VectorLayer} instead.
+ *
+ * Note that any property set in the options is set as a {@link module:ol/Object~BaseObject}
+ * property on the layer object; for example, setting `title: 'My Title'` in the
+ * options means that `title` is observable, and has get/set accessors.
