Where is the implementation of CancellationPromise defined?

[Cyberboss]

I was curious about the implementation details of Task.WaitAsync but came to a dead end with this struct.

runtime/src/libraries/System.Private.CoreLib/src/System/Threading/Tasks/Future.cs

Line 616 in cdd7566

return new CancellationPromise<TResult>(this, millisecondsTimeout, timeProvider, cancellationToken);

Is it an intrinsic?

Looks like it's defined in Task.cs.

Also PROTIP: Using the .NET Source Browser (as I did) makes looking for things like this a lot easier.

Oh, there it is. What's weird is it absolutely refuses to show up in a GitHub search:

Yeah, but Github search is the absolute worst.
