Struct syn::Signature [−][src]
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.
