kotlinx.coroutines.experimental.NonCancellable

All Implemented Interfaces:

Job
```
public class NonCancellable
implements Job
```
A non-cancelable job that is always active. It is designed to be used with run builder to prevent cancellation of code blocks that need to run without cancellation.
Use it like this:
run(NonCancellable) { // this code will not be cancelled }
