Error Manipulation Opcodes

This section documents instructions for creating and inspecting Error objects in CandleVM.

For operand encodings, see the executable format reference.

Errors

Opcode byte	Opcode	Operand bytes	Behavior
61	NewError	destination: register, message: register	Requires an ObjectRef value to a String, creates a custom CandleVM error containing that string, wraps it in an Error and stores the ObjectRef value.
62	ErrorType	destination: register, error: register	Requires an Error and stores the name of its CandleVM error type in a newly allocated String.
63	ErrorMessage	destination: register, error: register	Requires an Error and stores its message in a newly allocated String. For custom errors created by NewError, this is the original message; for other CandleVM errors, it is the runtime-generated message.
