1 //! This crates defines the trait resolution method and the type inference engine.
3 //! - **Traits.** Trait resolution is implemented in the `traits` module.
4 //! - **Type inference.** The type inference code can be found in the `infer` module;
5 //! this code handles low-level equality and subtyping operations. The
6 //! type check pass in the compiler is found in the `librustc_typeck` crate.
8 //! For more information about how rustc works, see the [rustc guide].
