Rust is new here, but it often does its dependency injection on the type-level (see the *_traits crates in servo, or anything involving piston - `https://github.com/piston-developers` https://github.com/piston-developers`). However, Rust doesn't have an OOP or Unit Test culture, so dependency injection is limited to true dependencies.
