Enum syn::FnArg

pub enum FnArg {
    Receiver(Receiver),
    Typed(PatType),
}

An argument in a function signature: the n: usize in fn f(n: usize).

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

Variants

Receiver(Receiver)

The self argument of an associated method, whether taken by value or by reference.

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

Typed(PatType)

A function argument accepted by pattern and type.
