Interface AsyncObserver

interpreter/async.go:48–53

Async extension function support. CEL supports `types.Unknown` as a first-class value, and concurrent (async) function execution in CEL invokes a stub function which checks for the presence of an existing result which matches the function call and call arguments, or which records the 'unexecuted' f
