safe_index 0.10.0

Type-safe indexes.
Documentation Documentation CI


Zero-cost-wraps usize-s to give them a specific type. The motivation is to have different kinds of indices that are incompatible at type-level, thus lowering the chance of mixing them up compared to using usize-s.

Index-type creation is done through a macro, so the type actually belong to the client crate. This lets users augment index-types with methods, trait implementations, etc.

See the documentation for details.
