Enum syn::GenericArgument

pub enum GenericArgument {
    Lifetime(Lifetime),
    Type(Type),
    Binding(Binding),
    Constraint(Constraint),
    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>.

Constraint(Constraint)

An associated type bound: Iterator<Item: Display>.

Const(Expr)

A const expression. Must be inside of a block.

NOTE: Identity expressions are represented as Type arguments, as they are indistinguishable syntactically.
