class Grape::Validations::Types::CustomTypeCollectionCoercer

See {CustomTypeCoercer} for details on types that will be supported by this by this coercer. This coercer works in the same way as CustomTypeCoercer except that it expects to receive an array of strings to coerce and will return an array (or optionally, a set) of coerced values.

CustomTypeCoercer is already capable of providing type checking for arrays where an independent coercion method is supplied. As such, CustomTypeCollectionCoercer does not allow for such a method to be supplied independently of the type.
