Trait Implementations

impl Store for BlobStore

fn get<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 Hash, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, StoreError>> + Send + 'async_trait>>

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

Retrieve data by hash Returns data or None if not found

fn put<'life0, 'async_trait>( &'life0 self, hash: Hash, bytes: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>

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

Store data by its hash Returns true if newly stored, false if already existed

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

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

Check if hash exists

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

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

Delete by hash Returns true if deleted, false if didn’t exist

fn put_many<'life0, 'async_trait>( &'life0 self, items: Vec<([u8; 32], Vec<u8>)>, ) -> Pin<Box<dyn Future<Output = Result<usize, StoreError>> + Send + 'async_trait>>

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

Store multiple blobs. Returns the number of newly stored items.

fn put_many_optimistic<'life0, 'async_trait>( &'life0 self, items: Vec<([u8; 32], Vec<u8>)>, ) -> Pin<Box<dyn Future<Output = Result<usize, StoreError>> + Send + 'async_trait>>

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

Store a locally generated content-addressed batch without requiring an implementation to reread bytes for hashes it already tracks.

fn flush_pending<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize, StoreError>> + Send + 'async_trait>>

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

Flush writes retained by an overlay store.

fn flush_pending_if_needed<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize, StoreError>> + Send + 'async_trait>>

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

Flush at an intermediate memory boundary. Buffered stores may retain a bounded amount between boundaries; callers must still explicitly flush all pending writes before returning a committed root.

fn get_range<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 [u8; 32], start: u64, end_inclusive: u64, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, StoreError>> + Send + 'async_trait>>

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

Retrieve a byte range from a blob by hash.

fn blob_size<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 [u8; 32], ) -> Pin<Box<dyn Future<Output = Result<Option<u64>, StoreError>> + Send + 'async_trait>>

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

Return the stored blob size in bytes.

fn delete_many<'life0, 'async_trait>( &'life0 self, hashes: Vec<[u8; 32]>, ) -> Pin<Box<dyn Future<Output = Result<usize, StoreError>> + Send + 'async_trait>>

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

Delete multiple hashes and return the number that existed.

fn set_max_bytes(&self, _max: u64)

Set maximum storage size in bytes. 0 = unlimited.

fn max_bytes(&self) -> Option<u64>

Get maximum storage size. None = unlimited.

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

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

Get storage statistics

fn evict_if_needed<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64, StoreError>> + Send + 'async_trait>>

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

Evict unpinned items if over storage limit. Returns number of bytes freed.

fn pin<'life0, 'life1, 'async_trait>( &'life0 self, _hash: &'life1 [u8; 32], ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

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

Pin a hash (increment ref count). Pinned items are not evicted.

fn unpin<'life0, 'life1, 'async_trait>( &'life0 self, _hash: &'life1 [u8; 32], ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

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

Unpin a hash (decrement ref count). Item can be evicted when count reaches 0.

fn pin_count(&self, _hash: &[u8; 32]) -> u32

Get pin count for a hash. 0 = not pinned.

fn is_pinned(&self, hash: &[u8; 32]) -> bool

Check if hash is pinned (pin count > 0)
