This library provides essentials types and trait to locate syntax elements.

- `Span` describes a byte range in a source file, with an intuitive API to write lexers and parsers.
- `Location<F>` combines a `Span` with a file identifier `F` to pin point a syntactic element in a source file.
- `Loc<T, F>` wraps any value `T` and bind it to its location.

Extra traits are also provided to extend common types (`Option`, `Result`, etc.) with localization functions.
The crate integrates well with diagnostic reporting libraries such as
[`codespan-reporting`](https://crates.io/crates/codespan-reporting) to render beautiful error reports.
