Enum apache_avro::Codec

source · [−]

pub enum Codec {
    Null,
    Deflate,
}

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.
