NewFileMetadata creates a basic FileMetadata entry for hdr.

FooterSizeSupported is the footer size supported by this implementation.

ManifestChecksumKey is a hexadecimal sha256 digest of the compressed manifest digest.

ManifestInfoKey is an annotation that signals the start of the TOC (manifest) contents which are embedded as a skippable zstd frame.

ManifestTypeCRFS is a manifest file compatible with the CRFS TOC file.

TarSplitInfoKey is an annotation that signals the start of the "tar-split" metadata contents which are embedded as a skippable zstd frame.

TypeChunk is special; in zstd:chunked not only are files individually compressed and indexable, there is a "rolling checksum" used to compute "chunks" of individual file contents, that are also added to the TOC.

The following types correspond to regular types of entries that can appear in a tar archive.

FileMetadata is an entry in the TOC that includes both generic file metadata that duplicates what can found in the tar header (and should match), but also special/custom content (see below).

TOC is short for Table of Contents and is used by the zstd:chunked file format to effectively add an overall index into the contents of a tarball; it also includes file metadata.

ZstdChunkedFooterData contains all the data stored in the zstd:chunked footer.
