This is to resolve the issue raised by PR #279 (and early PR #172). We are facing a dilemma:
polling
3.x is the latest release going forward but itsPoller.add()
is unsafe.polling
2.x has a safePoller.add()
but will eventually become un-maintained / less-maintained.One of things I want to keep for this crate is "all safe code". And I found
mio
can also do sockets polling with a safe API and a stable1.0
release. Hence this patch.And, as
mio
1.0 requires rustc 1.70, we bump our Rust version to 1.70.0.
