Struct ImplicitCtxt

source
pub struct ImplicitCtxt<'a, 'tcx> {
    pub tcx: TyCtxt<'tcx>,
    pub query: Option<QueryJobId>,
    pub diagnostics: Option<&'a Lock<ThinVec<DiagInner>>>,
    pub query_depth: usize,
    pub task_deps: TaskDepsRef<'a>,
}
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.
