ShortGuid

简短的URL安全Base64编码的UUID。

ShortGuids 透明地表示UUID类型，但它们的字符串表示中只使用22个字符，而带破折号的UUID有36个字符，不带破折号的UUID有32个字符。

#[test]
fn it_works() {
    let uuid = Uuid::try_parse("c9a646d3-9c61-4cb7-bfcd-ee2522c8f633").unwrap();
    let from_uuid = ShortGuid::from(uuid);
    let parsed_uuid = ShortGuid::try_parse("c9a646d3-9c61-4cb7-bfcd-ee2522c8f633").unwrap();
    let parsed_short = ShortGuid::try_parse("yaZG05xhTLe_ze4lIsj2Mw").unwrap();

    assert_eq!(from_uuid, uuid);
    assert_eq!(from_uuid, "yaZG05xhTLe_ze4lIsj2Mw");
    assert_eq!(from_uuid, "c9a646d3-9c61-4cb7-bfcd-ee2522c8f633");
    assert_eq!(from_uuid, parsed_uuid);
    assert_eq!(from_uuid, parsed_short);

    let random = ShortGuid::new_random();
    assert_ne!(from_uuid, random);
}

模糊测试

这使用 cargo-fuzz。请参阅 fuzz/fuzzers 以获取可用的模糊测试脚本。要运行，使用以下调用之一

cargo +nightly fuzz run roundtrip
cargo +nightly fuzz run decode_random
cargo +nightly fuzz run encode_random
cargo +nightly fuzz run equals
