std::suspend_never::await_ready
constexpr bool await_ready() const noexcept { return true; }
Always returns true, indicating that an await expression never suspends.
std::suspend_never::await_suspend
constexpr void await_suspend( std::coroutine_handle <> ) const noexcept {}
Does nothing.
std::suspend_never::await_resume
constexpr void await_resume() const noexcept {}
Does nothing. An await expression does not produce a value if suspend_never is used.
