Trait Implementations

impl BlobService for MemoryBlobService

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

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

Check if the service has the blob, by its content hash. On implementations returning chunks, this must also work for chunks.

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

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

Request a blob from the store, by its content hash. On implementations returning chunks, this must also work for chunks.

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

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

Insert a new blob into the store. Returns a BlobWriter, which implements tokio::io::AsyncWrite and a BlobWriter::close to finalize the blob and get its digest.

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

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

Return a list of chunks for a given blob. There’s a distinction between returning Ok(None) and Ok(Some(vec![])). The former return value is sent in case the blob is not present at all, while the second one is sent in case there’s no more granular chunks (or the backend does not support chunking). A default implementation checking for existence and then returning it does not have more granular chunks available is provided.

impl Clone for MemoryBlobService

fn clone(&self) -> MemoryBlobService

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for MemoryBlobService

fn default() -> MemoryBlobService

Returns the “default value” for a type.
