impl Cache for MemoryCache

fn worth_storing( &self, _cost: Duration, _bytes: usize, _kind: PayloadKind, ) -> bool

A hit is a memcpy, so anything computed is kept until the budget says otherwise.

fn sweep(&self)

The read time is the tick load stamped the entry with.

fn max_bytes(&self) -> u64

fn held_bytes(&self) -> u64

fn evicted_bytes(&self) -> u64

fn holds(&self, key: Hash) -> bool

fn load(&self, key: Hash, node: &str, expected: Expected) -> Option<Entry>

fn store( &self, key: Hash, payload: &Payload, traces: &[FilterTrace], label: Option<&Label>, )

fn faults(&self) -> u64

fn dir(&self) -> Option<&Path>

impl Default for MemoryCache

fn default() -> MemoryCache

Returns the “default value” for a type.
