Struct Cache 

pub struct Cache<CN, CF> {
    instance_name: String,
    near: CN,
    far: CF,
}

Asks near first, if not found, asks far. If found in there, returns it, and inserts it into near. There is no negative cache.

Fields

instance_name: String

near: CN

far: CF

Implementations

impl<BN, BF> Cache<BN, BF>

pub fn new(instance_name: String, near: BN, far: BF) -> Self

Constructs a new Cache from the passed instance_name, near and far BlobStores.

Trait Implementations

impl<BN, BF> BlobStore for Cache<BN, BF>

where BN: BlobStore, BF: BlobStore,

fn put<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 B3Digest, blob_meta: BlobMeta, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

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

Persists a BlobMeta for the given blob digest.

fn get<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 B3Digest, ) -> Pin<Box<dyn Future<Output = Result<Option<BlobMeta>, Error>> + Send + 'async_trait>>

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

Retrieves a BlobMeta for a given blob digest.

fn has<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 B3Digest, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

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

Checks if a BlobMeta for a given blob exists.
