Simulation status

[perlindgren]

Problem

As of now evaluating (clock) have no return value. So its not possible for the simulator to know if e.g., a halt condition has been encountered.

Solution

Introducing a return type for the Component::clock method.

Something like

enum Condition {
  Error(String),
  Halt(String),
}

And let clock return Result<(),Condition>, where Ok(()) indicates that clocking was successful, and Condition some type of exception. We can later refine the Condition to be more specific if we like but this could work to start out with.

• [x] basics as per PR https://github.com/perlindgren/syncrim/pull/58
• [ ] handling of Condition in the simulator, allowing run to halt/error etc.
• [ ] handling of Condition and Simulator status in vizia.
• [ ] handling of Condition and Simulator status in egui.

PR https://github.com/perlindgren/syncrim/pull/58 should address the basics, and we can work based on that.
