Speaking personally, I am pretty interested rust, although I haven't had the time to do much with it. This topic has come up before on other freebsd mailing lists, and realistically rust is not going to show up as part of the base system anytime soon. People need to write compelling applications in rust, where those applications are valuable enough that *they* (those new applications) need to be in the base system. (where "application" could include low-level code such as device drivers) Right now users who are interested in rust can install it via the ports tree. My experience with rust on macOS is that it takes a long time to compile, so I'd suggest using 'pkg install rust' if you want it on FreeBSD. Reminder: I am pretty interested in rust as a language, so you don't need to sell me on the *idea* of rust. But I would not expect to see it as part of the base system in less than 18 months. It would have to come in as part of a new major-version of FreeBSD, and (IMO) it's already too late to get it into what will become 13-release. What you need to do is to get a group of like-minded developers together, and have that group develop some really compelling improvements to the FreeBSD base system which are written in rust. -- Garance Alistair Drosehn = drosih@rpi.edu Lead developer@RPI also gad@FreeBSD.org Rensselaer Polytechnic Institute; Troy, NY; USA
