//! This crates defines the type inference engine.
//!
//! - **Type inference.** The type inference code can be found in the `infer` module;
//!   this code handles low-level equality and subtyping operations. The
//!   type check pass in the compiler is found in the `rustc_hir_analysis` crate.
//!
//! For more information about how rustc works, see the [rustc dev guide].
