Compilation error

Hey,

I get the following compilation error:

Compiling ocmu64 v0.1.0 (/home/philipp/2024-pace-submissions/exact/16-mjdv/ocmu64-pace-2024)
error[E0599]: no method named `chunk_by` found for mutable reference `&mut Vec<node::Node<node::BT>>` in the current scope

For more information about this error, try `rustc --explain E0599`.
error: could not compile `ocmu64` (lib) due to previous error
warning: build failed, waiting for other jobs to finish...

Any idea what's going wrong? (I have never used Rust before unfortunately)

Hey,

This was recently stabilized, in Rust 1.77, which released March 21. Are you using rust via rustup? If so, try rustup update stable.

If you're using, say, a debian packed version that's a bit behind, I can rewrite the code to not use this function.

That worked, thank you! I had Rust 1.75 installed via apt, I now uninstalled it and used rustup to install Rust 1.77 and the code compiled.
