Module std::encoding::compress

Compression and decompression (gzip, deflate, zlib).

Compress and decompress binary data using gzip, raw deflate, or zlib formats. Compression helpers take and return bytes values. Decompression callers must pass an explicit max_output_len to fail closed on oversized payloads; a conservative starting point is 64 * 1024 * 1024.

Examples

import std::encoding::compress;

fn main() {
    let data: bytes = bytes::new();
    data.push(72);
    data.push(101);
    data.push(108);
    data.push(108);
    data.push(111);
    let compressed = compress.gzip_compress(data);
    let decompressed = compress.gzip_decompress(compressed, 64 * 1024 * 1024);
    println(decompressed.len());  // 5
}
