[][src]Enum syn::FnArg

pub enum FnArg {
    SelfRef(ArgSelfRef),
    SelfValue(ArgSelf),
    Captured(ArgCaptured),
    Inferred(Pat),
    Ignored(Type),
}

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.

Syntax tree enum

This type is a syntax tree enum.

Variants

SelfRef(ArgSelfRef)

Self captured by reference in a function signature: &self or &mut self.

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

SelfValue(ArgSelf)

Self captured by value in a function signature: self or mut self.

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

Captured(ArgCaptured)

An explicitly typed pattern captured by a function signature.

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

Inferred(Pat)

A pattern whose type is inferred captured by a function signature.

Ignored(Type)

A type not bound to any pattern in a function signature.
