build error: type annotations needed

I'm trying to install uiua with cargo install uiua on rust 1.85.0 and get the following error

   Compiling hound v3.5.1
   Compiling uiua v0.14.1
error[E0283]: type annotations needed

   = note: multiple `impl`s satisfying `usize: PartialOrd<_>` found in the following crates: `core`, `deranged`:

             where the constant `MIN` has type `usize`, the constant `MAX` has type `usize`;

I think this is a weird Rust bug. It doesn't break for some versions.
Regardless, it was fixed on main a little while ago.

[donpdonp]

okay I tried updating rust to 1.85.1, but the error is the same. I'll wait until the next release.

This should be fixed with newest main, no?
