Crate rustc

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

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.

Note

This API is completely unstable and subject to change.
