Enum CatalogCompression 

pub enum CatalogCompression {
    Uncompressed,
    Snappy,
    Gzip,
    Brotli,
    Lz4,
    Zstd,
}

Compression codec for the data files a catalog writes.

Displays and serializes as the lowercase codec name, such as zstd; FromStr ignores ASCII case. lz4 writes Parquet LZ4_RAW and also parses from lz4_raw. LZO has no variant because the Parquet writer cannot produce LZO files.
