Thread safe, byte bounded record cache.

Implementations

impl RecordCache

pub fn new(capacity: u64) -> Self

A cache holding up to capacity bytes of records. Zero disables it.

pub fn get(&self, locator: u64) -> Option<MemoryNode>

The cached node for locator, counting a hit or a miss.

pub fn insert(&self, locator: u64, node: MemoryNode, charge: u64)

Cache node for locator, charged charge bytes, replacing any previous entry. A record larger than the whole cache is not cached.

pub fn invalidate(&self, locator: u64)

Drop the entry for locator, if cached.

pub fn set_capacity(&self, capacity: u64)

Change the capacity, evicting as needed to fit the new bound.

pub fn capacity(&self) -> u64

Configured capacity in bytes.

pub fn stats(&self) -> BufferStats

Activity counters and residency.
