Description

Builds are currently non-deterministic because rust-toolchain contains "nightly" meaning "use the latest nightly release of Rust". This can cause build seemingly random build failure in CI. I propose we modify rust-toolchain to refer to a specific nightly release e.g. "nightly-2019-07-31" so that builds are deterministic.

We can update this nightly version when needed (e.g. to pick up new features) as part of the regular PR process.
