pub(crate) fn unevaluated_param(ty: &Type) -> Option<UnevaluatedParam>Expand description
Detect an unevaluated-argument parameter type, matched on the last path
segment like the other markers: Quoted, Quosure, or one of them as the
type argument of Missing<..>. Any other position (Option<Quoted>,
&Quoted) is not one; mentions_unevaluated_marker lets the caller
refuse it.
