pub use rustc_lint_defs as lint;

Some facilities for tracking how codegen-units are reused during incremental compilation. This is used for incremental compilation tests and debug output.
code_stats 🔒
Contains infrastructure for configuring the compiler, including parsing command-line options.
the rustc crate store interface. This also includes types that are mostly used as a part of that interface, but these should probably get a better home if someone can find one.
A module for searching for libraries
options 🔒
Related to out filenames of compilation (e.g. save analysis, binaries).
Contains ParseSess which holds state living beyond what one Parser might. It also serves as an input to the parser itself.
session 🔒


Declares a static item of type &'static Lint.
Declares a type named $name which implements LintPass. To the right of => a comma separated list of Lint statics is given.
Implements LintPass for $ty with the given list of Lint statics.


Metadata associated with an item.
New-type wrapper around usize for representing limits. Ensures that comparisons against limits are consistent throughout the compiler.
Represents the data associated with a compilation session for a single crate.
A StableCrateId is a 64-bit hash of a crate name, together with all -Cmetadata arguments, and some other data. It is to CrateNum what DefPathHash is to DefId. It is stable across compilation sessions.


The behavior of the CTFE engine when an error occurs with regards to backtraces.
Holds data on the current incremental compilation session, if there is one.


Requirements for a StableHashingContext to be used in this crate. This is a hack to allow using the HashStable_Generic derive macro instead of implementing everything in rustc_middle.
