Error
This type represents an Error.

StorageType = DTypePointer[uint8, 0]:
Fields
- data (
DTypePointer[uint8, 0]): A pointer to the beginning of the string data being referenced. - loaded_length (
Int): The length of the string being referenced. Error instances conditionally own their error message. To reduce the size of the error instance we use the sign bit of the length field to store the ownership value. When loaded_length is negative it indicates ownership and a free is executed in the destructor.
