Example #1

File: write_cache.go Project: ipfs/go-blocks

// WriteCached returns a blockstore that caches up to |size| unique writes (bs.Put).
func WriteCached(bs Blockstore, size int) (Blockstore, error) {
	c, err := lru.New(size)
	if err != nil {
		return nil, err
	}
	return &writecache{blockstore: bs, cache: c}, nil
}

Example #2

File: datastore.go Project: ipfs/go-blocks

// NewDatastore constructs a new LRU Datastore with given capacity.
func NewDatastore(capacity int) (*Datastore, error) {
	cache, err := lru.New(capacity)
	if err != nil {
		return nil, err
	}

	return &Datastore{cache: cache}, nil
