Struct rustc_typeck::middle::ty::BinderExperimental

pub struct Binder<T>(pub T);

Binder is a binder for higher-ranked lifetimes. It is part of the compiler's representation for things like for<'a> Fn(&'a int) (which would be represented by the type PolyTraitRef == Binder<TraitRef>). Note that when we skolemize, instantiate, erase, or otherwise "discharge" these bound reons, we change the type from Binder<T> to just T (see e.g. liberate_late_bound_regions).
