Fields§

§tcx: TyCtxt<'tcx>§thir: &'a Thir<'tcx>§hir_context: HirId

The HirId of the current scope, which would be the HirId of the current HIR node, modulo adjustments. Used for lint levels.

§safety_context: SafetyContext

The current “safety context”. This notably tracks whether we are in an unsafe block, and whether it has been used.

§body_unsafety: BodyUnsafety§body_target_features: &'tcx [Symbol]

The #[target_feature] attributes of the body. Used for checking calls to functions with #[target_feature] (RFC 2396).

§assignment_info: Option<(Ty<'tcx>, Span)>

When inside the LHS of an assignment to a field, this is the type of the LHS and the span of the assignment expression.

§in_union_destructure: bool§param_env: ParamEnv<'tcx>§inside_adt: bool
