Struct ImplicitParamCollector 

pub(crate) struct ImplicitParamCollector<'a, 'genv, 'tcx> {
    resolver: &'a CrateResolver<'genv, 'tcx>,
    scopes: Vec<Option<(BinderKind, NodeId)>>,
    implicit_params: UnordMap<NodeId, Vec<ParamDef>>,
    errors: Errors<'genv>,
}

Collects the implicitly scoped params bound in each scope (see Scope::Implicit), reporting binders used in a position where they are not allowed.

Fields

resolver: &'a CrateResolver<'genv, 'tcx>

scopes: Vec<Option<(BinderKind, NodeId)>>

For each enclosing scope, the kind and node of the binder scope, or None if the scope is not a binder scope.

implicit_params: UnordMap<NodeId, Vec<ParamDef>>

errors: Errors<'genv>
