Struct rustc::ty::Generics [−] [src]

pub struct Generics<'tcx> {
    pub types: VecPerParamSpace<TypeParameterDef<'tcx>>,
    pub regions: VecPerParamSpace<RegionParameterDef>,
}
Unstable (rustc_private)

fn is_global(&self) -> bool

Indicates whether this value references only 'global' types/lifetimes that are the same regardless of what fn we are in. This is used for caching. Errs on the side of returning false. Read more
