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.

incr_comp_session: Option<&'tcx IncrCompSession>

dep_graph: DepGraph

prof: SelfProfilerRef

This duplicates Session::prof because this field is hot enough that accessing it via self.sess.prof is a measurable slowdown (see #161332).

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>

caches: GlobalCaches<'tcx>

data_layout: TargetDataLayout

Data layout specification for the current target.

alloc_map: AllocMap<'tcx>

Stores memory for globals (statics/consts).

current_gcx: CurrentGcx

Implementations

impl<'tcx> GlobalCtxt<'tcx>

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

where 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.
