Struct rustc_ap_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.

Fields

inputs: Vec<Param>

output: FnRetTy

Methods

impl FnDecl

pub fn get_self(&self) -> Option<ExplicitSelf>

pub fn has_self(&self) -> bool

pub fn c_variadic(&self) -> bool
