How define dynamic type

[krajcikondra]

Hi,

i have general type Filter which looks like:

			'name' => 'FilterInput',
			'fields' => [
				'field' => [
					'type' => Type::nonNull(Type::string()), 
					'description' => 'Field/column to filter'
				],
				'value' => [
					'type' => Type::nonNull(Type::string()), // can be string or integer or float
					'description' => 'Value to filter'
				],
				'operator' => [
					'type' => Type::nonNull(Type::string()),
					'description' => 'lt, le, eq, in, between, ge, gt'
				],
			]

I need define value type as string or integer or float. It is some way to define it?
