Struct CacheLayer

Source

pub struct CacheLayer {
    pub videos: VideoCache,
    pub downloads: DownloadCache,
    pub playlists: PlaylistCache,
}

Expand description

Consolidated cache layer combining video, download, and playlist caches.

Created from a CacheConfig and stored as Option<Arc<CacheLayer>> on the Downloader. Each sub-cache uses its own TTL from the config, falling back to its domain-specific default.

Fields§

§videos: VideoCache

Video metadata cache (tiered L1/L2).

§downloads: DownloadCache

Downloaded file metadata cache (tiered L1/L2).

§playlists: PlaylistCache

Playlist metadata cache (tiered L1/L2).

Implementations§

Source §

impl CacheLayer

Source

pub async fn from_config(config: &CacheConfig) -> Result<Self>

Build a CacheLayer from a CacheConfig.

§Arguments

config - The cache configuration specifying directories, TTLs, and backend settings.

§Returns

A new CacheLayer with all three domain caches initialized.

§Errors

Returns an error if any backend initialization fails.

Source

pub async fn clean(&self) -> Result<()>

Clean expired entries across all caches.

§Errors

Returns an error if cleanup fails for any sub-cache.

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
