Struct InMemoryBlobStore 

pub struct InMemoryBlobStore { /* private fields */ }

Arc<RwLock<HashMap<Digest, Bytes>>> reference implementation.

Cheap to clone; multiple handles share the same backing map. Useful for tests, ephemeral caches, and a baseline for performance comparison against custom backends.

Implementations

impl InMemoryBlobStore

pub fn new() -> Self

Construct an empty store.

pub fn len(&self) -> usize

Number of stored blobs.

pub fn is_empty(&self) -> bool

true when the store holds no blobs.

pub fn clear(&self)

Drop every entry.

Trait Implementations

impl BlobStore for InMemoryBlobStore

fn put<'life0, 'life1, 'async_trait>( &'life0 self, digest: &'life1 Digest, bytes: Bytes, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Write bytes under digest. See trait-level documentation for atomicity and digest-verification requirements.

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

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

Read the bytes stored under digest.

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

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

Check for blob presence without fetching the body.

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

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

Remove the blob keyed by digest. Deleting a missing blob is not an error.

fn list<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Digest>>> + Send + 'async_trait>>

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

Enumerate every blob currently stored.

impl Clone for InMemoryBlobStore

fn clone(&self) -> InMemoryBlobStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemoryBlobStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryBlobStore

fn default() -> InMemoryBlobStore

Returns the “default value” for a type.
