Thanks for your reply. @josevalim Works with installing rustup. The asdf plugin for rust I found has no nightly rust?!
Compiling takes a while. During compilation the explorer version was denoted as 0.1. How do I check that?
The week of the year function was working.

The explorer internal library in Rust is always 0.1 but that’s not a concern. It is always internal and never published.
