#[non_exhaustive]
pub enum CompressionAlgo {
    None,

Expand description

Identifies which algorithm was used to produce a CompressionResult.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

None

No compression — data is stored verbatim.

§

Rle

Run-length encoding: (count, value) pairs.

§

DeltaEncoding

Delta encoding: first byte + signed deltas.

§

Lz77Lite

Simplified LZ77 sliding-window compression.

§

DictionaryCoding

Dictionary coding: symbol table + indices.

§

HuffmanCoding

Huffman coding: variable-length prefix codes.

§

OxiLz4

LZ4 via oxiarc-lz4 (COOLJAPAN policy). Fast, moderate compression.

§

OxiZstd

Zstandard via oxiarc-zstd (COOLJAPAN policy). Balanced speed/ratio.

§

OxiBrotli

Brotli via oxiarc-brotli (COOLJAPAN policy). High compression for text.
