Preserving manually selected features across updates

[tranzystorekk]

Does cargo-update know about any features that were selected during install, or does it do updates with only the defaults?

Case in point: cargo-expand has the prettyplease feature that has to be enabled by hand, and I'm wondering if it's lost on each update?

It doesn't, because, fundamentally, that is not saved anywhere in the Cargo metadata. You can run cargo install-update-config -f prettyplease cargo-expand which will also enable the feature on subsequent updates (i.e. by installing via cargo install --features=prettyplease cargo-expand).

Thank you for the info!
