Struct syn::Signature

pub struct Signature {
    pub constness: Option<Const>,
    pub asyncness: Option<Async>,
    pub unsafety: Option<Unsafe>,
    pub abi: Option<Abi>,
    pub fn_token: Fn,
    pub ident: Ident,
    pub generics: Generics,
    pub paren_token: Paren,
    pub inputs: Punctuated<FnArg, Comma>,
    pub variadic: Option<Variadic>,
    pub output: ReturnType,
}

A function signature in a trait or implementation: unsafe fn initialize(&self).

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