# uuid

RFC 4122 version 4 (random) UUIDs, sourced from `/dev/urandom` and portable across macOS, Linux, and BSD.

The surface is small: `Uuid::new_v4() -> Option[Uuid]`, `Uuid::parse(s: str) -> Option[Uuid]`, and `uuid.to_string() -> string` (infallible, formatting into a stack `[u8; 37]` buffer).

```cplus
import "uuid/uuid" as uuid;

guard let option::Option::Some(u) = uuid::Uuid::new_v4() else { return 1; };
println(u.to_string().as_str());   // "550e8400-e29b-41d4-a716-446655440000"
```
