This module converts path templates in Elasticsearch::Role::API such as /{index}/{type}/{id} into real paths such as /my_index/my_type/123.
path_init() use Elasticsearch::Util::API::Path qw(path_init);
$handler = path_init($template);
$path = $handler->(\%params);
The path_init() sub accepts a path template and returns an anonymous sub which converts \%params into a real path, removing the keys that it has used from %params, eg:
$handler = path_init('/{indices}/_search');
$params = { index => ['foo','bar'], size => 10 };
$path = $handler->($params);
Would result in:
$path: '/foo,bar/_search';
$params: { size => 10 };
