[Rust] Update nightly: Oct 2020 Edition #26265
Description
We should update to a more recent nighly after the 2.0.0 release. It carries some clippy annoyances, which will mean that I have to revert much of what I did around float comparisons.
Might also be preferable to do this sooner, so that we can complete the clippy integration and throw away the carrot in favour of the stick.
