src/cmd/linuxkit/spec/cache.go:19–19

FindDescriptor find the descriptor pointed to by the reference in the cache. ref is a valid reference, such as docker.io/library/alpine:3.15 or alpine@sha256:4edbd2beb5f78b1014028f4fbb99f3237d9561100b6881aabbf5acce2c4f9454 If both tag and digest are provided, will use digest exclusively. Will expand

(ref *reference.Spec)

	// Will expand to full names, so "alpine" becomes "docker.io/library/alpine:latest".
	// If none is found, returns nil Descriptor and no error.
	FindDescriptor(ref *reference.Spec) (*v1.Descriptor, error)
	// ImagePull takes an image name and pulls it from a registry to the cache. It should be
	// efficient and only write missing blobs, based on their content hash. If the ref already
	// exists in the cache, it should not pull anything, unless alwaysPull is set to true.
