## Features
- A [dependency injection](https://en.wikipedia.org/wiki/Dependency_injection) container
- Autowiring dependencies
-- Binding factories
- API inspired from the one of [InversifyJS](https://github.com/inversify/InversifyJS)
- Helpful error messages
- Enforces the use of interface traits
+## Optional features
+- Binding factories (Rust nightly required)
+
+To use these features, you must [enable it in Cargo](https://doc.rust-lang.org/cargo/reference/features.html#dependency-features).

## Motivation
Other DI libraries for Rust are either unmaintained ([di](https://crates.io/crates/di) for example),
overcomplicated and or bloated ([anthill-di](https://crates.io/crates/anthill-di) for example)
