[][src]Struct rustc_ast::ast::FnHeader

pub struct FnHeader {
    pub unsafety: Unsafe,
    pub asyncness: Async,
    pub constness: Const,
    pub ext: Extern,

A function header.

All the information between the visibility and the name of the function is included in this struct (e.g., async unsafe fn or const extern "C" fn).
