# Struct cargo::ops::common_for_install_and_uninstall::CrateListingV2

source ·

    struct CrateListingV2 {
        installs: BTreeMap<PackageId, InstallInfo>,
        other: BTreeMap<String, Value>,
    }

Expand description

Tracking information for the set of installed packages.

## Fields§

§`installs: BTreeMap<PackageId, InstallInfo>`

Map of every installed package.

§`other: BTreeMap<String, Value>`

Forwards compatibility. Unknown keys from future versions of Cargo will be stored here and retained when the file is saved.

## Implementations§

source§

### impl CrateListingV2

source

#### fn sync_v1(&mut self, v1: &CrateListingV1)

Incorporate any changes from v1 into self. This handles the initial upgrade to v2, and handles the case where v2 is in use, and a v1 update is made, then v2 is used again. i.e., `cargo +new install foo ; cargo +old install bar ; cargo +new install bar` For now, v1 is the source of truth, so its values are trusted over v2.
