pub enum CompressionAlgo {
None,
Lz4,
Zstd {
level: i32,
},
Snappy,
Rle,
}Expand description
Compression algorithm used (or to be used) by a pipeline stage.
Variants§
None
No compression — data is stored as-is.
Lz4
LZ77-style sliding-window compressor (pure Rust, simplified).
Zstd
Zstandard-inspired: dispatches to RLE for level ≤ 3, LZ4-style for level ≥ 4.
Snappy
Snappy-inspired: same algorithm as Lz4.
Rle
Run-Length Encoding — pairs of (count, byte).
