[Bug] Worker running which encounters an unknown workflow type will exit

[bdbelevate]

What are you really trying to do?

I'm trying to run a worker using the (alpha) rust SDK so I'm not sure if this is a bug or is just not supported. But currently if a worker is running and an unknown workflow type is encountered on the same task queue, then the worker will exit with the error Workflow type {workflow_type} not found

Describe the bug

When a worker is running and an unknown workflow type is encountered on the same task queue, then the worker will exit with the error Workflow type {workflow_type} not found

This happens in this line of code:

https://github.com/temporalio/sdk-core/blob/master/sdk/src/lib.rs#L405

Is this intended behavior and if so, what is the suggested solution? Or is this simply unimplemented at this stage.

Minimal Reproduction

1. Start a worker using the rust lib.
2. Create a workflow that has a different workflow type then what you defined.
3. The worker will exit.

@bdbelevate This just isn't implemented right now. It should fail the workflow task instead. You're welcome to make a PR if you're interested :)
