Struct BlockCache

Source

pub struct BlockCache { /* private fields */ }

Expand description

Standalone in-memory LRU cache for blocks.

This is a building block; most callers should prefer CachedBlockStore.

Implementations§

Source §

impl BlockCache

Source

pub fn new(capacity: usize) -> Self

Create a new LRU cache with the given capacity (number of blocks).

Source

pub fn get(&self, cid: &Cid) -> Option<Block>

Get a block from cache.

Source

pub fn put(&self, block: Block)

Put a block into cache.

Source

pub fn remove(&self, cid: &Cid)

Remove a block from cache.

Source

pub fn clear(&self)

Clear the cache and reset counters.

Source

pub fn stats(&self) -> LegacyCacheStats

Return a legacy-style statistics snapshot.

Source

pub fn len(&self) -> usize

Current number of cached entries.

Source

pub fn is_empty(&self) -> bool

true if the cache is empty.
