T::Boolean.cast 'true'  # => true
T::Boolean.cast 'FALSE' # => false
T::Boolean.cast 'text'  # => Rasti::Types::CastError: Invalid cast: 'text' -> Rasti::Types::Boolean

T::Time['%Y-%m-%d'].cast '2016-10-22' # => 2016-10-22 00:00:00 -0300
T::Time['%Y-%m-%d'].cast '2016-10'    # => Rasti::Types::CastError: Invalid cast: '2016-10' -> Rasti::Types::Time['%Y-%m-%d']
