Rust
//! 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 `rustc_const_eval` crate.
|
|
//! - **Types.** The internal representation of types used in rustc is
|
|
//! defined in the [`ty`] module. This includes the
|
|
//! [**type context**][ty::TyCtxt] (or `tcx`), which is the central
|
|
//! context during most of compilation, containing the interners and
|
|
//! other things.
|
|
//!
|
|
//! For more information about how rustc works, see the [rustc dev guide].
|

|

|
|
//! This API is completely unstable and subject to change.
