Thx!

= help: add #![feature(const_fn_trait_bound)] to the crate attributes to enable

I'm using this toolchain:

active toolchain

nightly-x86_64-apple-darwin (default)
rustc 1.61.0-nightly (3b348d932 2022-02-19)

This has been answered by another user here:

rustup default nightly, and then rerun. It's accessing nightly features. I can confirm that it builds using cargo 1.61.0-nightly (65c8266 2022-03-09) on linux.

I'm hence closing the issue, feel free to reopen if it's still an issue for you.
