NAME

Path::Dispatcher::Match - the result of a successful rule match

SYNOPSIS

    my $rule = Path::Dispatcher::Rule::Tokens->new(
        tokens => [ 'attack', qr/^\w+$/ ],
        block  => sub {
            my $match = shift;
            attack($match->pos(2))
        },
    );
    my $match = $rule->match("attack dragon");
    # introspection
    $match->path                # "attack dragon"
    $match->leftover            # empty string (populated with prefix rules)
    $match->rule                # $rule
    $match->positional_captures # ["attack", "dragon"] (decided by the rule)
    $match->pos(1)              # "attack"
    $match->pos(2)              # "dragon"
