Struct NoCacheStrictLocalProvider 

pub struct NoCacheStrictLocalProvider {
    pub root: PathBuf,
    pub layer: usize,
}

NoCacheStrictLocalProvider defines a providers which serves local files without caching, which is useful for development and testing.

The main purpose of using this provider is to support annil for anni workspace.

Fields

root: PathBuf

Root directory of an strict annil

layer: usize

Hash layers

Trait Implementations

impl AnniProvider for NoCacheStrictLocalProvider

fn albums<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<HashSet<Cow<'_, str>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

During the list operation, the provider will scan the whole library and return all available albums.

Here available means the album directory exists and is not empty. The non-empty assumption is made because a workspace may create an empty directory for further use.

fn get_audio<'life0, 'life1, 'async_trait>( &'life0 self, album_id: &'life1 str, disc_id: NonZeroU8, track_id: NonZeroU8, range: Range, ) -> Pin<Box<dyn Future<Output = Result<AudioResourceReader>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a reader implements AsyncRead for content reading

fn get_cover<'life0, 'life1, 'async_trait>( &'life0 self, album_id: &'life1 str, disc_id: Option<NonZeroU8>, ) -> Pin<Box<dyn Future<Output = Result<ResourceReader>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a cover of corresponding album

fn reload<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Reloads the provider for new albums

fn has_album<'life0, 'life1, 'async_trait>( &'life0 self, album_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns whether given album exists

fn get_audio_info<'life0, 'life1, 'async_trait>( &'life0 self, album_id: &'life1 str, disc_id: NonZeroU8, track_id: NonZeroU8, ) -> Pin<Box<dyn Future<Output = Result<AudioInfo>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get audio info describing basic information of the audio file.
