Variants
Trap(Trap)
Trap happened.
NotResumable
The invocation is not resumable.
Invocations are only resumable if a host function is called, and the host function returns a trap of Host
kind. For other cases, this error will be returned. This includes:
- The invocation is directly a host function.
- The invocation has not been started.
- The invocation returns normally or returns any trap other than
Host
kind.
This error is returned by resume_execution
.
AlreadyStarted
The invocation has already been started.
This error is returned by start_execution
.
