Enum syn::GenericArgument
[−]
[src]
pub enum GenericArgument { Lifetime(Lifetime), Type(Type), Binding(Binding), Const(Expr), }
An individual generic argument, like 'a
, T
, or Item = T
.
This type is available if Syn is built with the "derive"
or "full"
feature.
Variants
Lifetime(Lifetime)
A lifetime argument.
Type(Type)
A type argument.
Binding(Binding)
A binding (equality constraint) on an associated type: the Item = u8
in Iterator<Item = u8>
.
Const(Expr)
A const expression. Must be inside of a block.
NOTE: Identity expressions are represented as Type arguments, as they are indistinguishable syntactically.
