Expand description
This is the implicit state of rustc. It contains the current
TyCtxt
and query. It is updated when creating a local interner or
executing a new query. Whenever there’s a TyCtxt
value available
you should also have access to an ImplicitCtxt
through the functions
in this module.
Fields§
§tcx: TyCtxt<'tcx>
The current TyCtxt
.
query: Option<QueryJobId>
The current query job, if any. This is updated by JobOwner::start
in
ty::query::plumbing
when executing a query.
diagnostics: Option<&'a Lock<ThinVec<DiagInner>>>
Where to store diagnostics for the current query job, if any.
This is updated by JobOwner::start
in ty::query::plumbing
when executing a query.
query_depth: usize
Used to prevent queries from calling too deeply.
task_deps: TaskDepsRef<'a>
The current dep graph task. This is used to add dependencies to queries when executing them.

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.
