	PAXRecords map[string]string `json:"pax_records,omitempty"`
}

FileMetadata represents the metadata that can be set on files in a layer

type LayerMetadata

type LayerMetadata struct {
	Defaults      *FileMetadata
	FileOverrides map[string]*FileMetadata
	// contains filtered or unexported fields
}

LayerMetadata holds all metadata configuration for a layer

func ParseLayerMetadata

func ParseLayerMetadata(defaultJSON string, fileMetadata map[string]string) (*LayerMetadata, error)

ParseLayerMetadata parses the default metadata and file-specific metadata

func (*LayerMetadata) ApplyToHeader

func (lm *LayerMetadata) ApplyToHeader(hdr *tar.Header, pathInImage string) error

ApplyToHeader applies the metadata to a tar header, with file-specific overrides taking precedence This implements the tree.MetadataProvider interface

func (*LayerMetadata) VerifyAllFileMetadataUsed

func (lm *LayerMetadata) VerifyAllFileMetadataUsed() error

VerifyAllFileMetadataUsed checks if all file metadata entries have been used at least once Returns an error if any entries are unused, listing all unused paths
