ShortGuid

Short URL-safe Base64 encoded UUIDs.

ShortGuids transparently represent UUID types but use only 22 characters in their string representation, as opposed to 36 characters for a dashed UUID or 32 without dashes.

```rust

[test]

fn itworks() { let uuid = Uuid::tryparse("c9a646d3-9c61-4cb7-bfcd-ee2522c8f633").unwrap(); let fromuuid = ShortGuid::from(uuid); let parseduuid = ShortGuid::tryparse("c9a646d3-9c61-4cb7-bfcd-ee2522c8f633").unwrap(); let parsedshort = ShortGuid::tryparse("yaZG05xhTLeze4lIsj2Mw").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);

} ```

Fuzzing

This uses cargo-fuzz. See fuzz/fuzzers for the available fuzzing scripts. To run, use an invocation like these:

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