pub enum ResumableError {
    Trap(Trap),
    NotResumable,
    AlreadyStarted,
}
Expand description

A resumable invocation error.

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.

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more
