SYNOPSIS
        use AnyEvent::Memcached;

        my $memd = AnyEvent::Memcached->new(
        servers => [ "10.0.0.15:11211", "10.0.0.15:11212" ], # same as in Cache::Memcached
        debug   => 1,
        compress_threshold => 10000,
        namespace => 'my-namespace:',

        cv      => $cv, # AnyEvent->condvar: group callback
        );

    $memd->set_servers([ "10.0.0.15:11211", "10.0.0.15:11212" ]);

    # Basic methods are like in Cache::Memcached, but with additional cb => sub { ... };
        # first argument to cb is return value, second is the error(s)

    $memd->set( key => $value, cb => sub {
        shift or warn "Set failed: @_"
        } );

        $memd->get( 'key', cb => sub {
        my ($value,$err) = shift;
        $err and return warn "Get failed: @_";
        warn "Value for key is $value";
        } );

        $memd->mget( [ 'key1', 'key2' ], cb => sub {
        my ($values,$err) = shift;
        $err and return warn "Get failed: @_";
        warn "Value for key1 is $values->{key1} and value for key2 is $values->{key2}"
        } );

        # Additionally there is rget (see memcachedb-1.2.1-beta)

        $memd->rget( 'fromkey', 'tokey', cb => sub {
        my ($value,$err) = shift;
        $err and warn "Get failed: @_";
        } );

METHODS
  new %args
    Currently supported options:

    servers =item namespace =item debug =item cv =item compress_threshold
    =item compress_enable

  set_servers
        Setup server list

  connect
        Establish connection to all servers and invoke event C<connected>, when ready

  set( $key, $value, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Unconditionally sets a key to a given value in the memcache.

    $rc is

    '1' Successfully stored

    '0' Item was not stored

    undef
        Error happens, see $err

  add( $key, $value, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Like "set", but only stores in memcache if the key doesn't already
    exist.

  replace( $key, $value, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Like "set", but only stores in memcache if the key already exists. The
    opposite of add.

  append( $key, $value, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Append the $value to the current value on the server under the $key.

    append command first appeared in memcached 1.2.4.

  prepend( $key, $value, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Prepend the $value to the current value on the server under the $key.

    prepend command first appeared in memcached 1.2.4.

  get( $key, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Retrieve the value for a $key. $key should be a scalar

  mget( $keys : ARRAYREF, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    NOT IMPLEMENTED YET

    Retrieve the values for a $keys.

  get_multi : Alias for mget.
    NOT IMPLEMENTED YET

  gets( $keys : ARRAYREF, [cv => $cv], [ expire => $expire ], cb => $cb->( $rc, $err ) )
    Retrieve the value and its CAS for a $key. $key should be a scalar.

    NOT IMPLEMENTED YET

  delete( $key, [cv => $cv], [ noreply => 1 ], cb => $cb->( $rc, $err ) )
    Delete $key and its value from the cache.

    If "noreply" is true, cb doesn't required

  del
    Alias for "delete"

  remove
    Alias for "delete"

  incr( $key, $increment, [cv => $cv], [ noreply => 1 ], cb => $cb->( $rc, $err ) )
    Increment the value for the $key by $delta. Starting with memcached
    1.3.3 $key should be set to a number or the command will fail. Note that
    the server doesn't check for overflow.

    If "noreply" is true, cb doesn't required, and if passed, simply called
    with rc = 1

    Similar to DBI, zero is returned as "0E0", and evaluates to true in a
    boolean context.

  decr( $key, $decrement, [cv => $cv], [ noreply => 1 ], cb => $cb->( $rc, $err ) )
    Opposite to "incr"

  rget( $from, $till, [ max => 100 ], [ '+left' => 1 ], [ '+right' => 1 ], [cv => $cv], cb => $cb->( $rc, $err ) )
    Memcachedb 1.2.1-beta implements rget method, that allows to look
    through the whole storage

    $from
        the starting key

    $till
        finishing key

    +left
        If true, then starting key will be included in results. true by
        default

    +right
        If true, then finishing key will be included in results. true by
        default

    max Maximum number of results to fetch. 100 is the maximum and is the
        default
