Struct parquet_format_safe::CompressionCodec

source ·
pub struct CompressionCodec(pub i32);
Expand description

Supported compression algorithms.

Codecs added in format version X.Y can be read by readers based on X.Y and later. Codec support may vary between readers based on the format version and libraries available at runtime.

See Compression.md for a detailed specification of these algorithms.
