Enum rustc_ast::ast::GenericBound
source · pub enum GenericBound {
Trait(PolyTraitRef, TraitBoundModifier),
Outlives(Lifetime),
}
Expand description
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.
