Struct memcache

pkg/v1/cache/cache_test.go:130–132

memcache is an in-memory Cache implementation. It doesn't intend to actually write layer data, it just keeps a reference to the original Layer. It only assumes/considers compressed layers, and so only writes layers by digest.

// It only assumes/considers compressed layers, and so only writes layers by
// digest.
type memcache struct {
	m map[v1.Hash]v1.Layer
}

func (m *memcache) Put(l v1.Layer) (v1.Layer, error) {
	digest, err := l.Digest()
