Overview ¶
Package memory is an in-process cache backend. It stores values in a sync-protected map, evicts on TTL check, and is safe for concurrent use.
Memory is the default backend for tests and single-process applications that do not need cross-process cache coherence. For multi-instance deployments use hex/cache/redis or hex/cache/memcached (opt-in).

Types ¶
type Cache ¶
type Cache struct {
// contains filtered or unexported fields
}
Cache is an in-memory cache implementation.
func WithClock ¶
WithClock returns a Cache using now for time. Intended for tests that need to advance time deterministically instead of sleeping.
func (*Cache) Increment ¶
Increment atomically adds delta to the value at key. Absent keys start from zero and take no expiration. Non-numeric existing values return an error.
