Expand description

See TyCtxt for details about this type.

Fields§

§arena: &'tcx WorkerLocal<Arena<'tcx>>§hir_arena: &'tcx WorkerLocal<Arena<'tcx>>§interners: CtxtInterners<'tcx>§sess: &'tcx Session§crate_types: Vec<CrateType>§stable_crate_id: StableCrateId

The stable_crate_id is constructed out of the crate name and all the -C metadata arguments passed to the compiler. Its value forms a unique global identifier for the crate. It is used to allow multiple crates with the same name to coexist. See the rustc_symbol_mangling crate for more information.

§lint_store: Lrc<dyn Any + DynSync + DynSend>

This only ever stores a LintStore but we don’t want a dependency on that type here.

FIXME(Centril): consider dyn LintStoreMarker once we can upcast to Any for some additional type safety.

§dep_graph: DepGraph§prof: SelfProfilerRef§types: CommonTypes<'tcx>

Common types, pre-interned for your convenience.

§lifetimes: CommonLifetimes<'tcx>

Common lifetimes, pre-interned for your convenience.

§consts: CommonConsts<'tcx>

Common consts, pre-interned for your convenience.

§hooks: Providers

Hooks to be able to register functions in other crates that can then still be called from rustc_middle.

§untracked: Untracked§query_system: QuerySystem<'tcx>§query_kinds: &'tcx [DepKindStruct<'tcx>]§ty_rcache: Lock<FxHashMap<CReaderCacheKey, Ty<'tcx>>>§pred_rcache: Lock<FxHashMap<CReaderCacheKey, Predicate<'tcx>>>§selection_cache: SelectionCache<'tcx>

Caches the results of trait selection. This cache is used for things that do not have to do with the parameters in scope.

§evaluation_cache: EvaluationCache<'tcx>

Caches the results of trait evaluation. This cache is used for things that do not have to do with the parameters in scope. Merge this with selection_cache?

§new_solver_evaluation_cache: EvaluationCache<'tcx>

Caches the results of goal evaluation in the new solver.

§new_solver_coherence_evaluation_cache: EvaluationCache<'tcx>§data_layout: TargetDataLayout

Data layout specification for the current target.

§alloc_map: Lock<AllocMap<'tcx>>

Stores memory for globals (statics/consts).
