//! 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].
//!
//! [rustc dev guide]: https://rustc-dev-guide.rust-lang.org/
//!
//! # Note
//!
//! This API is completely unstable and subject to change.
