@alamb Either I have something misconfigured locally or this change breaks compilation with the version 1.52.1 configured in rust-toolchain:
error: invalid fragment specifier `pat_param`

= help: valid fragment specifiers are `ident`, `block`, `stmt`, `expr`, `pat`, `ty`, `lifetime`, `literal`, `path`, `meta`, `tt`, `item` and `vis`

@alamb I think we need to somehow pin the rust toolchain

Just noticed rust-toolchain file is not part of the repo and I only added that locally at some point. That means this was actually a problem on my side, arrow-rs requiring a newer version is totally fine.

@jhorstmann -- I backported this change to the proposed arrow 5.3.0. Given your experience, I think I should probably undo that change and make a new 5.3.0 RC candidate.
@jimexist / @jhorstmann any thoughts?

it's either that or you note in the release notes that the minimal support rust version is 1.53.
rust edition 2021 is likely land in rust 1.56. and given my understanding that arrow does not promise a specific back-compatible yet I feel like that users are supposed to upgrade to latest stable. but my understanding could be wrong.

I now also remember that discussion and agree with it. So from my perspective it is not necessary to revert this change.
We should probably write down this policy in the README if it is not already there yet.
