Types

type Cache

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

A Cache is a fixed-size LRU cache of blob contents. It is safe for concurrent access.

func New

func New(size int) *Cache

New constructs a blob cache that stores at most size bytes worth of blobs.

func (*Cache) Add

func (c *Cache) Add(id restic.ID, blob []byte) (old []byte)

Add adds key id with value blob to c. It may return an evicted buffer for reuse.

func (*Cache) Get
