injectables 0.1.0

A procedural macro library that enables field injection between Rust structs through #[injectable] and #[inject_fields] attributes. The library handles visibility rules, generic type resolution, and detects circular dependencies during compile time to ensure safe composition. This enables a declarative approach to struct composition where fields from one or more source structs can be automatically injected into target structs while respecting Rust's ownership and visibility rules.
