Crate rustc_session

Re-exports

cgu_reuse_tracker
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.
errors
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

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.

Attribute
A syntax-level representation of an attribute.
CompilerIO
FieldInfo
Limit
New-type wrapper around usize for representing limits. Ensures that comparisons against limits are consistent throughout the compiler.
Limits
MarkedAttrs
OptimizationFuel
PerfStats
Session
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

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

DEFAULT_LOCALE_RESOURCE
Raw content of Fluent resource for this crate, generated by fluent_messages macro, imported by rustc_driver to include all crates’ resources in one bundle.

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.
