       JSON::Validator::Util - Utility functions for JSON::Validator

       JSON::Validator::Util is	a package containing utility functions for
       JSON::Validator.	Each of	the "FUNCTIONS"	can be imported.

	 $str =	data_checksum $any;

       Will create a checksum for any data structure stored in $any.

	 $str =	data_section "Some::Module", "file.json";
	 $str =	data_section "Some::Module", "file.json", {encode => 'UTF-8'};

       Same as "data_section" in Mojo::Loader, but will	also look up the file
       in any inherited	class.

	 $str =	data_type $any;
	 $str =	data_type $any,	[@schemas];
	 $str =	data_type $any,	[{type => "integer", ...}];

       Returns the JSON	type for $any. $str can	be array, boolean, integer,
       null, number object or string. Note that	a list of schemas need to be
       provided	to differentiate between "integer" and "number".

	 $bool = is_type $any, $class;
	 $bool = is_type $any, $type; #	$type =	"ARRAY", "BOOL", "HASH", "NUM" ...

       Checks if $any is a, or inherits	from, $class or	$type. Two special
       types can be checked:

       o BOOL

	 Checks	if $any	is a boolean value. $any is considered boolean if it
	 is an object inheriting from JSON::PP::Boolean	or is another object
	 that stringifies to "1" or "0".

       o NUM

	 Checks	if $any	is indeed a number.

	 $str =	json_pointer $path, $append;

       Will concat $append on to $path,	but will also escape the two special
       characters "~" and "/" in $append.

	 @errors = prefix_errors $prefix, @errors;

       Consider	this internal for now.

	 $data	     = schema_extract $any, $json_pointer;
	 $data	     = schema_extract $any, "/x/cool_beans/y";
	 $collection = schema_extract $any, ["x", undef, "y"];
	 schema_extract	$any, $json_pointer, sub { my ($data, $json_pointer) = @_ };

       The basic usage is to extract data from $any, using a $json_pointer -
       RFC 6901	<>. It can however be	used
       in a more complex way by	passing	in an array-ref, instead of a plain
       string. The array-ref can contain "undef()" values, will	result in
       extracting any element on that point, regardsless of value. In that
       case a Mojo::Collection will be returned.

       A callback can also be given. This callback will	be called each time
       the $json_pointer matches some data, and	will pass in the $json_pointer
       at that place.

       In addition, if the $json_pointer points	to a JSON::Validator::Ref at
       any point, the "$ref" will be followed, while if	you used
       Mojo::JSON::Pointer, it would return either the JSON::Validator::Ref or

       Even though "schema_extract" has	special	capabilities for handling a
       JSON-Schema, it can be used for any data-structure, just	like

	 $str =	schema_type $hash_ref;
	 $str =	schema_type $hash_ref, $any;

       Looks at	$hash_ref and tries to figure out what kind of type the	schema
       represents. $str	can be "array",	"const", "number", "object", "string",
       or fallback to empty string if the correct type could not be figured

       $any can	be provided to double check the	type, so if $hash_ref
       describes an "object", but $any is an array-ref,	then $str will become
       an empty	string.	Example:

	 # $str	= "";
	 $str =	schema {additionalProperties =>	false},	[];

	 # $str	= "object"
	 $str =	schema {additionalProperties =>	false};
	 $str =	schema {additionalProperties =>	false},	{};

       Note that this process is relatively slow, so it	will make your
       validation faster if you	specify	"type".	Both of	the two	below is
       valid, but the one with "type" will be faster.

	 {"type": "object", "properties": {}} #	Faster
	 {"properties":	{}}		      #	Slower
