We've updated the minimum-required rust version for mozilla-central to 1.15.1.
This version just reached the stable channel, so you'll need to update your build environment. You should be able to do this just by typing: rustup update stable If you don't have rustup, you can get it by running `./mach bootstrap` or directly from https://rustup.rs/ The major new feature in this release is the stabilization of "custom derive" procedural macros, which greatly simplify compile-time code generation. This is important for the IPC code we're using in webrender and the audio remoting work. The change for this is currently on the autoland branch and should be merged later today. https://bugzilla.mozilla.org/show_bug.cgi?id=1337153 As always, please feel free to contact me if you run into issues getting rust working in your build or if you have other questions.
