   = note: this warning originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)

MSRV for 2.x branch is 1.24, but this change would bump it to 1.32. I think you're going to have to live with it. Strategically placed #[allow(deprecated)] might help.

[U007D]

Ah, thanks--good to know.

@CreepySkeleton Would a PR with #[allow(deprecated)] on the macro-generated code be accepted? It's quite annoying to have a deprecation warning on every build.

[pksunkara]

@jhpratt Go ahead.
