Struct rustc_middle::ty::print::pretty::TraitRefPrintOnlyTraitPath

source ·
pub struct TraitRefPrintOnlyTraitPath<'tcx>(TraitRef<'tcx>);
Expand description

Wrapper type for ty::TraitRef which opts-in to pretty printing only the trait path. That is, it will print Trait<U> instead of <T as Trait<U>>.
