Functions

func IsForeignLayer

func IsForeignLayer(desc ocispec.Descriptor) bool

IsForeignLayer checks if a descriptor describes a foreign layer.

func IsManifest

IsManifest checks if a descriptor describes a manifest.

func Plain

func Plain(desc ocispec.Descriptor) ocispec.Descriptor

Plain returns a plain descriptor that contains only MediaType, Digest and Size.

Types

type Descriptor

type Descriptor struct {
	// MediaType is the media type of the object this schema refers to.
	MediaType string `json:"mediaType,omitempty"`

	// Digest is the digest of the targeted content.
	Digest digest.Digest `json:"digest"`

	// Size specifies the size in bytes of the blob.
	Size int64 `json:"size"`
}

Descriptor contains the minimun information to describe the disposition of targeted content. Since it only has strings and integers, Descriptor is a comparable struct.

var Empty Descriptor

Empty is an empty descriptor

func FromOCI

func FromOCI(desc ocispec.Descriptor) Descriptor

FromOCI shrinks the OCI descriptor to the minimum.
