futures-test 0.3.7 removed the undocumented std_reexport
. Also, futures-core removed core_reexport
at some point, which also causes build failures.

Your crate is very close to what I need. However, I need one thing more: the ability to add and subtract permits. For example, I need to be able to acquire a SemaphoreGuard
with 10 permits and another with 5, then combine them into a single SemaphoreGuard
with 15. I also need to be able to do the reverse: split a single SemaphoreGuard
into two, with a selectable division of permits between them. Do you think this feature would be a useful addition to your library? If so, I'll try to add it.
