pub enum Codec {
    Null,
    Deflate,
    Snappy,
}
Expand description

The compression codec used to compress blocks.

Variants

Null

The Null codec simply passes through data uncompressed.

Deflate

The Deflate codec writes the data block using the deflate algorithm as specified in RFC 1951, and typically implemented using the zlib library. Note that this format (unlike the “zlib format” in RFC 1950) does not have a checksum.

Snappy

The Snappy codec uses Google’s Snappy compression library. Each compressed block is followed by the 4-byte, big-endian CRC32 checksum of the uncompressed data in the block.

Implementations

Compress a stream of bytes in-place.

Decompress a stream of bytes in-place.
