• OSFeatures of the target platform are the subsets of the OSFeatures array of the current platform.

Note: Variant, OSVersion and OSFeatures are optional fields, will skip the comparison if the target platform does not provide specfic value.

func SelectManifest(ctx context.Context, src content.ReadOnlyStorage, root ocispec.Descriptor, p *ocispec.Platform) (ocispec.Descriptor, error)
