Struct parquet_format_async_temp::CompressionCodec

pub struct CompressionCodec(pub i32);

Supported compression algorithms.

Codecs added in 2.4 can be read by readers based on 2.4 and later. Codec support may vary between readers based on the format version and libraries available at runtime. Gzip, Snappy, and LZ4 codecs are widely available, while Zstd and Brotli require additional libraries.
