Enum ImageIndex 

pub enum ImageIndex {
    Oci(OciIndex),
    Docker(DockerManifestList),
}

A unified index type that can represent either OCI or Docker formats.

Variants

Oci(OciIndex)

Docker(DockerManifestList)

Implementations

impl ImageIndex

pub fn from_bytes(data: &[u8]) -> Result<Self>

Parses an image index from JSON bytes, auto-detecting the format.

Detection is based on the mediaType field:

• Docker manifest list: application/vnd.docker.distribution.manifest.list.v2+json
• OCI index: application/vnd.oci.image.index.v1+json

Returns an error if mediaType is missing or unrecognized.

pub fn manifests(&self) -> &[Descriptor]

Returns the manifest descriptors.

pub fn media_type(&self) -> MediaType

Returns the media type of this index.

pub fn digest(&self) -> Result<Digest>

Computes the digest of this index.

pub fn to_bytes(&self) -> Result<Vec<u8>>

Serializes the index to JSON bytes.

pub fn find_platform( &self, arch: &str, os: &str, variant: Option<&str>, ) -> Option<&Descriptor>

Finds a manifest matching the given platform.

Trait Implementations

impl Clone for ImageIndex

fn clone(&self) -> ImageIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ImageIndex

fn eq(&self, other: &ImageIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
