parity-snappy

Rust 对 snappy 压缩库的绑定。

目前这个库使用 snappy v1.1.7。snappy 的源代码包含在 parity-snappy-sys 包中，因此无需预先安装 snappy，库将静态链接。

示例

use parity_snappy as snappy;

let input: Vec<u8> = ...;
let compressed = snappy::compress(&input);
let decompressed = snappy::decompress(&compressed);

assert_eq!(decompressed == input);

use parity_snappy as snappy;

let input: Vec<u8> = ...;
let mut compressed = Vec::with_capacity(snappy::max_compressed_len(input.len()));
let mut decompressed = Vec::with_capacity(input.len());

let len = snappy::compress_into(&input, &mut compressed);
let _ = snappy::decompress_into(&compressed[..len], &mut decompressed);

assert_eq!(decompressed == input);
