Data::TreeValidator::Constraints - A collection of constraints for validating data
use Data::TreeValidator::Constraints qw( required );
Constraints currently take a single form, a subroutine reference. If the data does not validate, an exception will be raised (which is caught by process methods). If an exception is not raised, the data will be assumed to be valid.
All methods below are available for importing into using modules
Checks that $input is defined, and stringifies to a true value (not the empty string)
Checks that a given input is between $min and $max. You do not have to specify both parameters, either or is also fine.
$min
$max
Checks that a given input is in the set defined by @options.
@options
Checks that a given input satisfies a given Moose::Meta::TypeConstraint. E.g.
use MooseX::Types::Moose qw/Num/; type(Num);
