[−][src]Enum rustc_hir::hir::GenericBound

pub enum GenericBound<'hir> {
    Trait(PolyTraitRef<'hir>, TraitBoundModifier),
    LangItemTrait(LangItem, Span, HirId, &'hir GenericArgs<'hir>),
    Outlives(Lifetime),
}

The AST represents all type param bounds as types. typeck::collect::compute_bounds matches these against the "special" built-in traits (see middle::lang_items) and detects Copy, Send and Sync.
