my $dns = DNS::Unbound->new(); my $query = $dns->resolve_async( 'example.com', 'A' ); # Ordinary ES6 Promise semantics: $query->then( .. )->then( .. ); $query->cancel();
This object represents the result of an asynchronous DNS::Unbound query. It implements a standard promise interface and also provides a cancellation mechanism.
In addition to the
finally() methods—see Promise::ES6 if you’re unsure of how to use those—this class provides:
Cancels an in-progress DNS query. Returns nothing.
NOTE: This will leave the promise unresolved.
