Enum AudioSource 

#[non_exhaustive]
pub enum AudioSource {
    Read(PathBuf),
    Download(Uri, Option<Txt>),
    Data(AudioHash, IpcBytes, AudioDataFormat),
    Audio(Var<AudioTrack>),
}

The different sources of an audio resource.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Read(PathBuf)

A path to an audio file in the file system.

Audio equality is defined by the path, a copy of the audio in another path is a different audio.

Download(Uri, Option<Txt>)

A uri to an audio resource downloaded using HTTP GET with an optional HTTP ACCEPT string.

If the ACCEPT line is not given, all audio formats supported by the view-process backend are accepted.

Audio equality is defined by the URI and ACCEPT string.

Data(AudioHash, IpcBytes, AudioDataFormat)

Shared reference to bytes for an encoded or decoded audio.

Audio equality is defined by the hash, it is usually the hash of the bytes but it does not need to be.

Inside AUDIOS the reference to the bytes is held only until the audio finishes decoding.

Audio(Var<AudioTrack>)

Already resolved (loaded or loading) audio.

The audio is passed-through, not cached.
