rust-smaz

rust-smaz是smaz算法的纯Rust实现，用于压缩非常短的字符串。有关smaz及其算法本身的信息，请参阅antirez的原始C实现smaz。

使用

将此添加到您的 Cargo.toml

[dependencies]
smaz = "0.1.0"

快速入门

extern crate smaz;

use smaz::{compress,decompress};

fn main() {
    let s = "string";

    let compressed = compress(&s.as_bytes());
    println!("compress bytes: {:?}", &compressed);

    let decompressed = decompress(&compressed).unwrap();
    let origin = str::from_utf8(&decompressed).unwrap();
    assert_eq!(s, origin);
}

lib.rs:

此crate实现了用于压缩非常短字符串的smaz算法。

Smaz不适用于压缩通用数据，但平均情况下可以压缩文本40-50%（对英文更有效），并且能够对HTML和URL进行一些压缩。重要的是，Smaz甚至可以压缩只有两个或三个字节的字符串！

快速入门

extern crate smaz;

use smaz::{compress,decompress};

fn main() {
    let s = "my long string";

    let compressed = compress(&s.as_bytes());
    println!("bytes: {:?}", &compressed);

    let decompressed = decompress(&compressed);
    if let Ok(v) = decompressed {
        println!("bytes: {:?}", &v);
    }
}
