Does it support structured concurrency in some way?

There are several ways to control and wait the sub coroutines

each created coroutine has a handle, you can join it to get the result, or just wait it to finish
you can cancel or kill a coroutine by

unsafe { j.coroutine().cancel() };

May also support scoped version spawn. which would block until all the scoped coroutine finished. ref example
the join! macro would block until all the block finish, it's basically a scoped spawn for convenience. ref example
the select! macro block until any coroutine finish. ref example
there is also advanced sub coroutine control mechanism called cqueue which is the underlying implementation of the previous macros.
