pub struct BlockVorbisComment {
    pub vendor_string: String,
    pub comments: Vec<UserComment>,
}
Expand description

Also known as FLAC tags, the contents of a vorbis comment packet as specified here (without the framing bit). Note that the vorbis comment spec allows for on the order of 2 ^ 64 bytes of data where as the FLAC metadata block is limited to 2 ^ 24 bytes. Given the stated purpose of vorbis comments, i.e. human-readable textual information, this limit is unlikely to be restrictive. Also note that the 32-bit field lengths are little-endian coded according to the vorbis spec, as opposed to the usual big-endian coding of fixed-length integers in the rest of FLAC.

The Vorbis text comment header is the second (of three) header packets that begin a Vorbis bitstream. It is meant for short, text comments, not arbitrary metadata; arbitrary metadata belongs in a separate logical bitstream (usually an XML stream type) that provides greater structure and machine parseability.

The comment field is meant to be used much like someone jotting a quick note on the bottom of a CDR. It should be a little information to remember the disc by and explain it to others; a short, to-the-point text note that need not only be a couple words, but isn’t going to be more than a short paragraph.

The essentials, in other words, whatever they turn out to be, eg: “Honest Bob and the Factory-to-Dealer-Incentives, I’m Still Around, opening for Moxy Früvous, 1997”
