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.
