Enum ChunkCodec

Source

pub enum ChunkCodec {
    None,
    Lz4,
    Zstd,
}

Expand description

Byte codec applied to a v4 chunk body.

Recorded per chunk, so a chunk that does not shrink is stored as ChunkCodec::None whatever the file was asked for.

Variants§

§

None

Body stored as is.

§

Lz4

lz4 block. Fastest to decode.

§

Zstd

zstd at a low level. Smaller than lz4, slower to decode.
