Enum odbc_avro::Codec

pub enum Codec {
    Null,
    Deflate,
}

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.

Methods

impl Codec

pub fn compress(&self, stream: &mut Vec<u8>) -> Result<(), Error>

Compress a stream of bytes in-place.

pub fn decompress(&self, stream: &mut Vec<u8>) -> Result<(), Error>

Decompress a stream of bytes in-place.
