Trait Implementations

impl Storage for MemCache

fn lookup<'life0, 'life1, 'async_trait>( &'static self, key: &'life0 CacheKey, _trace: &'life1 SpanHandle ) -> Pin<Box<dyn Future<Output = Result<Option<(CacheMeta, HitHandler)>>> + Send + 'async_trait>>

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

Lookup the storage for the given CacheKey

fn get_miss_handler<'life0, 'life1, 'life2, 'async_trait>( &'static self, key: &'life0 CacheKey, meta: &'life1 CacheMeta, _trace: &'life2 SpanHandle ) -> Pin<Box<dyn Future<Output = Result<MissHandler>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Write the given CacheMeta to the storage. Return MissHandler to write the body later.

fn purge<'life0, 'life1, 'async_trait>( &'static self, key: &'life0 CompactCacheKey, _trace: &'life1 SpanHandle ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

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

Delete the cached asset for the given key

fn update_meta<'life0, 'life1, 'life2, 'async_trait>( &'static self, key: &'life0 CacheKey, meta: &'life1 CacheMeta, _trace: &'life2 SpanHandle ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Update cache header and metadata for the already stored asset.

fn support_streaming_partial_write(&self) -> bool

Whether this storage backend supports reading partially written data

fn as_any(&self) -> &(dyn Any + Send + Sync)

Helper function to cast the trait object to concrete types
