1//! Faithful port of Luau `Location` (`Ast/include/Luau/Location.h`).
2//!
3//! A half-open source span `begin..end`. C++ defines `operator==`/`!=` (collapse
4//! into the derived `PartialEq`/`Eq`) but no ordering. `Default` is the
5//! all-zero span, matching the C++ `Location()` default constructor. The four
6//! `Location(...)` constructors and the `encloses`/`overlaps`/`contains`/
7//! `extend`/`shift` methods are separate items.
