Overview

Package memory is the legacy bounded, concurrency-safe LRU cache backend.

Deprecated: use github.com/faustbrian/go-cache/v2/adapters/memory. This package remains supported for the longer of 180 days after successor availability and two subsequently published stable root-module minor releases.

Types

type Backend 

type Backend struct {
	// contains filtered or unexported fields
}

Backend preserves the legacy memory adapter type identity.

func New 

func New(config Config) (*Backend, error)

New validates config and constructs an empty memory backend.

func (*Backend) Close 

func (backend *Backend) Close() error

Close releases retained entries and rejects subsequent operations.

func (*Backend) Delete 

func (backend *Backend) Delete(ctx context.Context, key string) (bool, error)

Delete removes key and reports whether it was present.

func (*Backend) Get 

func (backend *Backend) Get(ctx context.Context, key string) (cache.Record, bool, error)

Get returns a cloned live record or an explicit miss.

func (*Backend) Set 

func (backend *Backend) Set(
	ctx context.Context,
	key string,
	record cache.Record,
	condition cache.Condition,
) (bool, error)

Set atomically applies condition and stores a cloned record.

func (*Backend) Stats 

func (backend *Backend) Stats() Stats

Stats returns a synchronized snapshot of backend counters.

type Config 

type Config struct {
	MaxEntries int
	MaxBytes   int
	Clock      cache.Clock
	Observer   cache.Observer
}

Config defines hard entry and retained-byte limits for a Backend.

type Stats 

type Stats struct {
	Entries     int
	Bytes       int
	Evictions   uint64
	Expirations uint64
}

Stats is a snapshot of retained state and cumulative removals.
