Enum devise::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.
