pub fn top_decode_from_nested_or_exit<T, I, ExitCtx: Clone>(
    input: I, 
    c: ExitCtx, 
    exit: fn(_: ExitCtx, _: DecodeError) -> !
) -> T where
    I: TopDecodeInput,
    T: NestedDecode, 

Top-decodes the result using the NestedDecode implementation. Uses the fast-exit mechanism in case of error.
