Enum syntax::ast::GenericBound

pub enum GenericBound {
    Trait(PolyTraitRef, TraitBoundModifier),
    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.
