Enum syn::GenericParam

pub enum GenericParam {
    Type(TypeParam),
    Lifetime(LifetimeDef),
    Const(ConstParam),
}

A generic type parameter, lifetime, or const generic: T: Into<String>, 'a: 'b, const LEN: usize.

This type is available only if Syn is built with the "derive" or "full" feature.

Syntax tree enum

This type is a syntax tree enum.
