i got an error with message

''

when i just tried to commit, because

check_rust_formatting.sh

uses a "deprecated version of rustfmt", which requires the

--force

argument to succeed. the commit succeeded after i added that to the script (i didn't commit that change). the error message from manually running the

rustfmt

command was:

This version of rustfmt is deprecated. Use rustfmt-nightly. Use --force to run deprecated rustfmt.

not sure if this means we should just add

--force

or if there's another issue, or if it's somehow specific to my system
