NAME

IO::Async::Resolver::LibAsyncNS - use libasyncns for IO::Async resolver queries

SYNOPSIS

            

              
              
use IO::Async::Loop;
use IO::Async::Resolver::LibAsyncNS;
my $loop = IO::Async::Loop->new;
my $resolver = IO::Async::Resolver::LibAsyncNS->new;
$loop->add( $resolver );
$resolver->getaddrinfo(
   host => "metacpan.org",
   service => "http",
   socktype => "stream",
)->on_done( sub {
   my @res = @_;
   print "metacpan.org available at\n";
   printf "  family=%d addr=%v02x\n", $_->{family}, $_->{addr} for @res;
})->get;
            
          

DESCRIPTION

This subclass of IO::Async::Resolver applies special handling to the getaddrinfo_hash and getnameinfo resolvers to use a Net::LibAsyncNS instance, rather than using the usual IO::Async::Function wrapper around the system resolver functions. This may lead to higher performance in some applications.

It provides no additional methods, configuration options or events besides those supported by IO::Async::Resolver itself. It exists purely to implement the same behaviours in a more efficient manner.
