Flake refuses to build due to (I think?) outdated registry

[tukanoidd]

Just ran nix flake update and tried to rebuild my system. Got this:

error: builder for '/nix/store/39l6fhqc5ajzww8hmm9sd33y64rrn19d-watershot-0.2.2.drv' failed with exit code 101;

I checked to make sure the version of hyprland crate is in crates.io and tried to find info on how to fix this issue myself, but all I could find were outdated issues that talk about the old ways Rust packages were built with nixpkgs that don't apply today. Is there any way to fix this? Or should I just wait for nixpkgs to updater their version of the registry?

There's actually two issues here that cause it to fail in this instance (Hyprland on Nix). While #40 updated the code and Cargo.toml for Hyprland 0.40.0, it forgot to update Cargo.lock accordingly, causing a build failure. Additionally, the version of the Rust compiler from the nixpkgs input is now too old to build Watershot (this is not an issue if you override the input with your own nixpkgs). These issues are fixed by #45 and #37 respectively.
