=head1 NAME
Path::Dispatcher::Match - the result of a successful rule match
=head1 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"
$match->run # attack("dragon")
=head1 DESCRIPTION
If a L<Path::Dispatcher::Rule> successfully matches a path, it creates one or
more C<Path::Dispatcher::Match> objects.
=head1 ATTRIBUTES
=head2 rule
The L<Path::Dispatcher::Rule> that created this match.
=head2 path
The path that the rule matched.
=head2 leftover
The rest of the path. This is populated when the rule matches a prefix of the
path.
=head2 positional_captures
Any positional captures generated by the rule. For example,
L<Path::Dispatcher::Rule::Regex> populates this with the capture variables.
=head2 named_captures
Any named captures generated by the rule. For example,
L<Path::Dispatcher::Rule::Regex> populates this with named captures.
=head2 parent
The parent match object, if applicable (which may be set if this match is the
child of, for exampl, a L<Path::Dispatcher::Rule::Under> prefix)
=head1 METHODS
=head2 run
Executes the rule's codeblock with the same arguments.
=head2 pos($i)
Returns the C<$i>th positional capture, 1-indexed.
