Enum syntax::ast::TyParamBound

pub enum TyParamBound {
    TraitTyParamBound(PolyTraitRef, TraitBoundModifier),
    RegionTyParamBound(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.
