---------------------------------
Summary: [Rust] Pin to specific Rust nightly release
Key: ARROW-6100
URL: https://issues.apache.org/jira/browse/ARROW-6100
Project: Apache Arrow
Issue Type: Improvement
Components: Rust
Reporter: Andy Grove
Assignee: Andy Grove
Fix For: 0.15.0
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.
