An asynchronous start function is called immediately in the new job and must
return a StartObj, such as a job, generator, or promise. If a job or
promise is returned, it will be awaited and its result used to asynchronously
set the result of the returned job.
If a generator is returned, it will be run asynchronously, in the context of
the newly-started job. Any result it returns or error it throws will be
treated as the result of the job. If the job is canceled, the iterator's
.return() method will be called to abort it (thereby running any
try-finally clauses in the generator), and the result of the call will be
otherwise ignored.
Type Parameters
T
The type the job will end up returning
This = void
The type of this the function accepts, if using two-argument
start(). Defaults to void (for one-argument start()).
