Struct BlobCache 

Source 
pub struct BlobCache<B, H, S, T>
where
    B: BlobStoreGet<H>,
    H: HashProtocol,
    S: BlobSchema + 'static,
    T: TryFromBlob<S>,
    Handle<H, S>: ValueSchema,
{ /* private fields */ }
Expand description

Re-export of the blob cache wrapper. Lazy cache for blob conversions keyed by blob handle.

Implementations§

Source§

impl<B, H, S, T> BlobCache<B, H, S, T>
where B: BlobStoreGet<H>, H: HashProtocol, S: BlobSchema + 'static, T: TryFromBlob<S>, Handle<H, S>: ValueSchema,

Source

pub fn new(blobs: B) -> Self

Creates a new cache backed by blobs with the default capacity.

Source

pub fn with_capacity(blobs: B, capacity: usize) -> Self

Creates a new cache backed by blobs with the given entry capacity.

Source

pub fn get( &self, handle: Value<Handle<H, S>>, ) -> Result<Arc<T>, B::GetError<T::Error>>

Returns the cached value for handle, fetching and converting it on a cache miss.
