  the package `chomp` depends on `conv`, with features: `std` but `conv` does
not have these features.

I have no clue about the Rust ecosystem. Does that say a dependency is missing?

This is an upstream build failure. Please try updating the package, contact them and request a fix or fix it yourself and add the patch here.
