MediaType is an enumeration of the supported mime types that an element of an image might have.

The collection of known MediaType values.

func (MediaType) IsConfig 

func (m MediaType) IsConfig() bool

IsConfig returns true if the mediaType represents a config, as opposed to something else, like an image.

func (MediaType) IsDistributable 

func (m MediaType) IsDistributable() bool

IsDistributable returns true if a layer is distributable, see: https://github.com/opencontainers/image-spec/blob/master/layer.md#non-distributable-layers

func (MediaType) IsImage 

func (m MediaType) IsImage() bool

IsImage returns true if the mediaType represents an image manifest, as opposed to something else, like an index.

func (MediaType) IsIndex 

func (m MediaType) IsIndex() bool

IsIndex returns true if the mediaType represents an index, as opposed to something else, like an image.

func (MediaType) IsLayer 

func (m MediaType) IsLayer() bool

func (MediaType) IsSchema1 

func (m MediaType) IsSchema1() bool
