[][src]Struct rustc_ast::ast::FnDecl

pub struct FnDecl {
    pub inputs: Vec<Param>,
    pub output: FnRetTy,

A signature (not the body) of a function declaration.

E.g., fn foo(bar: baz).

Please note that it's different from FnHeader structure which contains metadata about function safety, asyncness, constness and ABI.
