Enum syn::FnArg

[−] Show declaration

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

[−] Expand description

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)

[−] Expand description

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

Note that self receivers with a specified type, such as self: Box<Self>, are parsed as a FnArg::Typed.

Typed(PatType)

[−] Expand description

A function argument accepted by pattern and type.
