        name: InternedString,

Expand description

Dependency edge information for fingerprints. This is generated for each dependency and is stored in a `Fingerprint`.

## Fields§

§`pkg_id: u64`

The hash of the package id that this dependency points to

§`name: InternedString`

The crate name we’re using for this dependency, which if we change we’ll need to recompile!

§`public: bool`

Whether or not this dependency is flagged as a public dependency or not.

§`only_requires_rmeta: bool`

Whether or not this dependency is an rmeta dependency or a “full” dependency. In the case of an rmeta dependency our dependency edge only actually requires the rmeta from what we depend on, so when checking mtime information all files other than the rmeta can be ignored.

§`fingerprint: Arc<Fingerprint>`

The dependency’s fingerprint we recursively point to, containing all the other hash information we’d otherwise need.
