> 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.
