Enum rustc_ast::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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
