Fields
tcx: TyCtxt<'tcx>
thir: Thir<'tcx>
param_env: ParamEnv<'tcx>
region_scope_tree: &'tcx ScopeTree
typeck_results: &'tcx TypeckResults<'tcx>
rvalue_scopes: &'tcx RvalueScopes
adjustment_span: Option<(HirId, Span)>
When applying adjustments to the expression
with the given HirId
, use the given Span
,
instead of the usual span. This is used to
assign the span of an overall method call
(e.g. my_val.foo()
) to the adjustment expressions
for the receiver.
body_owner: DefId
The DefId
of the owner of this body.
