Modules

Some facilities for tracking how codegen-units are reused during incremental compilation. This is used for incremental compilation tests and debug output.

code_stats

config

Contains infrastructure for configuring the compiler, including parsing command-line options.

cstore

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.

filesearch

A module for searching for libraries

options

output

Related to out filenames of compilation (e.g. save analysis, binaries).

parse

Contains ParseSess which holds state living beyond what one Parser might. It also serves as an input to the parser itself.

search_paths

session

utils

Macros

declare_lint

Declares a static item of type &'static Lint.

declare_lint_pass

Declares a type named $name which implements LintPass. To the right of => a comma separated list of Lint statics is given.

declare_tool_lint

impl_lint_pass

Implements LintPass for $ty with the given list of Lint statics.

Structs

Attribute

Metadata associated with an item.

FieldInfo

Limit

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.

StableCrateId

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.

VariantInfo

Enums

CtfeBacktrace

The behavior of the CTFE engine when an error occurs with regards to backtraces.

DataTypeKind

DiagnosticMessageId

Diagnostic message ID, used by Session.one_time_diagnostics to avoid emitting the same message more than once.

DiagnosticOutput

IncrCompSession

Holds data on the current incremental compilation session, if there is one.

SizeKind

Traits

HashStableContext

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.

SessionDiagnostic

Trait implemented by error types. This should not be implemented manually. Instead, use #[derive(SessionDiagnostic)] – see rustc_macros::SessionDiagnostic.
