Fields

arena: &'tcx WorkerLocal<Arena<'tcx>>

hir_arena: &'tcx WorkerLocal<Arena<'tcx>>

interners: CtxtInterners<'tcx>

sess: &'tcx Session

lint_store: Lrc<dyn Any + Sync + Send>

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.

untracked: Untracked

on_disk_cache: Option<&'tcx dyn OnDiskCache<'tcx>>

This provides access to the incremental compilation on-disk cache for query results. Do not access this directly. It is only meant to be used by DepGraph::try_mark_green() and the query infrastructure. This is None if we are not incremental compilation mode

queries: &'tcx dyn QueryEngine<'tcx>

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?

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.
