THRIFT-5819: use latest rustc version for rustlib

[jimexist]

use latest rustc version for rustlib

• Did you create an Apache Jira ticket? (Request account here, not required for trivial changes)
• If a ticket exists: Does your pull request title follow the pattern "THRIFT-NNNN: describe my issue"?
• Did you squash your changes to a single commit? (not required, but preferred)
• Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"?
• If your change does not involve any code, include [skip ci] anywhere in the commit message to free up build resources.

🤣 great catch

still pending some compile err that i didn't have time to look into. not sure if someone familiar with the rust stack can help.

This warning (which is turned into an error by #[deny(warnings)]) is coming from a doc test. It seems like having dead code in these is reasonable, so you can disable this like so:

thanks for the pointer. fwiw you can just submit a new PR - i don't use rust lib myself so i am not that much motivated to update this (nor be able to actually test the changes).

[cameron-martin]

I've tested it locally, running all the commands that the CI does, and I think that should resolve all the issues.

I can submit another PR, but it may take a few days before I can put that up.

[cameron-martin]

I've opened #3085 to succeed this PR.
