=head1 DESCRIPTION

This is the backend chosen if L or L are detected
in C<%INC>. It will execute the requests asynchronously
using L.

=head1 METHODS

=head2 C<< Future::HTTP::AnyEvent->new() >>

    my $ua = Future::HTTP::AnyEvent->new();

Creates a new instance of the HTTP client.

=head2 C<< $ua->is_async() >>

Returns true, because this backend is asynchronous.

=head2 C<< $ua->http_get($url, %options) >>

    $ua->http_get('http://example.com/',
        headers => {
            'Accept' => 'text/json',
        },
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    });

Retrieves the URL and returns the body and headers, like
the function in L.

=head2 C<< $ua->http_head($url, %options) >>

    $ua->http_head('http://example.com/',
        headers => {
            'Accept' => 'text/json',
        },
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    });

Retrieves the header of the URL and returns the headers,
like the function in L.

=head2 C<< $ua->http_post($url, $body, %options) >>

    $ua->http_post('http://example.com/api',
        '{token:"my_json_token"}',
        headers => {
            'Accept' => 'text/json',
        },
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    });

Posts the content to the URL and returns the body and headers,
like the function in L.

=head2 C<< $ua->http_request($method, $url, %options) >>

    $ua->http_request('PUT' => 'http://example.com/api',
        headers => {
            'Accept' => 'text/json',
        },
        body    => '{token:"my_json_token"}',
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    });

Posts the content to the URL and returns the body and headers,
like the function in L.
