#Guix folks, you might have noticed that tools that look for package dependents (‘guix refresh -l PKG’, ‘guix build -P1 PKG’) have suddenly become much faster.

We owe this to the new Rust packaging model that @hako just merged:

Surprised? Turns out that the previous ‘cargo-build-system’ would traverse the package graph multiple times to compute the closure of crates needed by each Rust package. Such a relief!
