|
//! The "main crate" of the Rust compiler. This crate contains common
|
|
//! type definitions that are used by the other crates in the rustc
|
|
//! "family". Some prominent examples (note that each of these modules
|
|
//! has their own README with further details).
|
|
//!
|
|
//! - **HIR.** The "high-level (H) intermediate representation (IR)" is
|
|
//! defined in the `hir` module.
|
|
//! - **MIR.** The "mid-level (M) intermediate representation (IR)" is
|
|
//! defined in the `mir` module. This module contains only the
|
|
//! *definition* of the MIR; the passes that transform and operate
|
|
//! on MIR are found in `librustc_mir` crate.
|
|
//! - **Types.** The internal representation of types used in rustc is
|
|
//! defined in the `ty` module. This includes the **type context**
|
|
//! (or `tcx`), which is the central context during most of
|
|
//! compilation, containing the interners and other things.
|
|
//! - **Traits.** Trait resolution is implemented in the `traits` module.
|
|
//! - **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 `librustc_typeck` crate.
|
|
//!
|
|
//! For more information about how rustc works, see the [rustc guide].
