FWIW, a spmc channel would also be incredibly useful, and could probably be optimized in ways a mpmc can not.

@jonhoo I started bulding a spmc lib for rust, though it needs optimizations, and I should probably dump the linked list idea.. oyashio/spmc lib

Any updates on this? :-)

[jonhoo]

https://github.com/jonhoo/bus could probably be adapted pretty easily to be spmc instead of sp-broadcast. Will probably simplify the code a fair amount in fact.

I believe crossbeam's SegQueue is a MPMC channel.
EDIT: SegQueue is non-blocking, but MsQueue looks more like a channel.

Any update on getting this into Rust core?

Would definitely be a useful feature. Is it to be integrated to rust 's sync library ?
