Struct cargo::core::registry::PackageRegistry

pub struct PackageRegistry<'cfg> {
    // some fields omitted
}

This structure represents a registry of known packages. It internally contains a number of Box<Source> instances which are used to load a Package from.

The resolution phase of Cargo uses this to drive knowledge about new packages as well as querying for lists of new packages. It is here that sources are updated (e.g. network operations) and overrides are handled.

The general idea behind this registry is that it is centered around the SourceMap structure, contained within which is a mapping of a SourceId to a Source. Each Source in the map has been updated (using network operations if necessary) and is ready to be queried for packages.
