//! Using the `uuid!` macro.
//!
//! `uuid!` will parse encoded UUIDs at compile time instead of at runtime.
//! If you've got a fixed UUID string handy then consider using `uuid!` instead
//! of `Uuid::parse_str` or `str::parse`.
//!
//! If you enable the `macro-diagnostics` feature, you can see much better
//! error messages.
