NAME

DataStore::CAS::FS::DirCodec::Minimal - Directory representation with minimal metadata

VERSION

version 0.0101

DESCRIPTION

This class packs a directory as a list of [type, hash, filename], which is very efficient, but omits metadata that you often would want in a backup.

This is primarily intended for making small frequent backups inbetween more thorough nightly backups.

METHODS

encode

  $serialized= $class->encode( \@entries, \%metadata )

Serialize the given entries into a scalar.

Serialize the bare minimum fields of each entry. Each entry will have 3 pieces of data saved: type, name, and ref.

The %metadata is encoded using JSON, which isn't very compact, but if you really want a minimal encoding you shouldn't supply metadata anyway.

decode

  $dir= $class->decode( %params )

Reverses encode, to create a Dir object.

See DirCodec->load for details on %params.
