const std::string &	name () const noexcept
	Returns the name being resolved.

const std::string &	service () const noexcept
	Returns the service being resolved.

bool	incomplete () const noexcept
	Returns true if the deadline expired, and the returned list of addresses is incomplete. Until `get()` is called, always is true.

result< span< address > >	get () noexcept
	Returns the array of addresses, blocking until completion if necessary, returning any error if one occurred.

result< void >	wait (deadline d={}) noexcept
	Wait for up the deadline for the array of addresses to be retrieved.
