trait bounds other than Sized on const fn parameters are unstable

[PhillyWebGuy]

This package is evidently a dependency of dependency for a repo I am working in. I just ran cargo update, went to compile, and now my code won't compile. I'm pretty new to Rust so I'm sort of at a loss as to what to do right now, particularly since this crate isn't even a dependency listed in any Cargo.toml file, thus I assume it is a dependency of a dependency.
