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).

Implementations

impl<'tcx> GlobalCtxt<'tcx>

pub fn enter<'a: 'tcx, F, R>(&'a self, f: F) -> Rwhere F: FnOnce(TyCtxt<'tcx>) -> R,

Installs self in a TyCtxt and ImplicitCtxt for the duration of f.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
