compress

Compression and decompression utilities supporting multiple algorithms.

Supported algorithms

Gzip, Zlib, Flate/Deflate, Zstd, Snappy (block format), LZ4 (frame format).

Key types

• Algorithm -- algorithm identifier (AlgGzip, AlgZstd, AlgSnappy, AlgLZ4, ...)
• Compression level constants: LevelNone, LevelBest, LevelFastest, LevelDefault

Key functions

• GzipCompress(data, level) / GzipDecompress(data)
• ZlibCompress(data, level) / ZlibDecompress(data)
• FlateCompress(data, level) / FlateDecompress(data)
• ZstdCompress(data) / ZstdDecompress(data)
• SnappyCompress(data) / SnappyDecompress(data)
• LZ4Compress(data) / LZ4Decompress(data)
• NewGzipWriter(w, level) / NewGzipReader(r) -- streaming helpers

Quick start

import "github.com/LingByte/ling-base/common/compress"

data := []byte("hello world hello world hello world")

compressed, err := compress.GzipCompress(data, compress.LevelBest)
if err != nil {
    log.Fatal(err)
}

decompressed, err := compress.GzipDecompress(compressed)
if err != nil {
    log.Fatal(err)
}
