    /// stream type, one can find more media-specific information in
    /// `DiscovererAudioInfo`, `DiscovererVideoInfo`, and
    /// `DiscovererContainerInfo`.
    ///
    /// The `DiscovererStreamInfo` represents the topology of the stream. Siblings
    /// can be iterated over with `DiscovererStreamInfoExt::get_next` and
    /// `DiscovererStreamInfoExt::get_previous`. Children (sub-streams) of a
    /// stream can be accessed using the `DiscovererContainerInfo` API.
    ///
    /// As a simple example, if you run `Discoverer` on an AVI file with one audio
    /// and one video stream, you will get a `DiscovererContainerInfo`
    /// corresponding to the AVI container, which in turn will have a
    /// `DiscovererAudioInfo` sub-stream and a `DiscovererVideoInfo` sub-stream
    /// for the audio and video streams respectively.
