Struct HashMapBlobStore

pub struct HashMapBlobStore { /* private fields */ }

A blob store that is backed by a hash map with a reference counted value. Used for tests when you need an actual blob store.

Trait Implementations

impl BlobStore for HashMapBlobStore

fn clone_blob(&mut self, hash: &BlobHash) -> Result<(), NoSuchBlobError>

Mark the hash as used.

fn insert_blob(&mut self, bytes: &[u8]) -> BlobHash

Insert bytes into the blob store.

fn insert_with_uses(&mut self, hash: &BlobHash, uses: usize, bytes: Box<[u8]>)

Insert hash referring to bytes and mark its refcount as uses.

fn retrieve_blob(&self, hash: &BlobHash) -> Result<&[u8], NoSuchBlobError>

Returns the bytes stored at the content address hash.

fn free_blob(&mut self, hash: &BlobHash) -> Result<(), NoSuchBlobError>

Marks the hash as unused.

fn iter_blobs(&self) -> BlobsIter<'_>

Iterate over all blobs present in the blob store.

fn bytes_used_by_blobs(&self) -> u64

Returns the amount of memory in bytes used by blobs in this BlobStore.

fn num_blobs(&self) -> u64

Returns the number of blobs, or more precisely, blob-usages, recorded in this BlobStore.

impl Debug for HashMapBlobStore

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

Formats the value using the given formatter.

impl Default for HashMapBlobStore

fn default() -> HashMapBlobStore

Returns the “default value” for a type.

impl MemoryUsage for HashMapBlobStore

fn heap_usage(&self) -> usize

The heap memory usage of this type. The default implementation returns 0.

impl PartialEq for HashMapBlobStore

fn eq(&self, other: &HashMapBlobStore) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
