Struct InProcessCache 

pub struct InProcessCache { /* private fields */ }

The OSS default single-replica tier: a bounded map with per-entry TTL (jittered), LRU eviction, a value-size bound, and single-flight miss coalescing via per-key locks.

Implementations

impl InProcessCache

pub fn new(capacity: usize, max_value_bytes: usize) -> Self

pub fn get_or_compute<F, E>( &self, namespace: &str, key: &str, ttl: Option<Duration>, compute: F, ) -> Result<Vec<u8>, E>

where F: FnOnce() -> Result<Vec<u8>, E>,

Single-flight compute-through: return a cached value, or compute it exactly once even under concurrent misses for the same key. A computed ERROR is propagated but NEVER cached.

pub fn len(&self) -> usize

Current entry count (test/introspection).

pub fn is_empty(&self) -> bool

Trait Implementations

impl CacheBackend for InProcessCache

fn get(&self, namespace: &str, key: &str) -> Option<Vec<u8>>

fn put(&self, namespace: &str, key: &str, value: Vec<u8>, ttl: Option<Duration>)

fn invalidate(&self, namespace: &str)

Flush every entry belonging to namespace (an emit on an invalidate_on: channel triggers this).

impl Default for InProcessCache

fn default() -> Self

Returns the “default value” for a type.
