Module cargo::core::registry

Types that hold source information for a group of packages.

The primary type you’re looking for is PackageRegistry. It is an abstraction over multiple Sources. PackageRegistry also implements the Registry trait, allowing a dependency resolver to query necessary package metadata (i.e., Summary) from it.

Not to be confused with crate::sources::registry and crate::ops::registry. The former is just one kind of source, while the latter involves operations on the registry Web API.

Structs

• LockedPatchDependency
  Argument to PackageRegistry::patch which is information about a [patch] directive that we found in a lockfile, if present.
• PackageRegistry
  This structure represents a registry of known packages. It internally contains a number of Source instances which are used to load a Package from.

Enums

• Kind 🔒
  Kinds of sources a PackageRegistry has loaded.

Traits

• Registry
  An abstraction provides a set of methods for querying source information about a group of packages, without leaking too much implementation details of the actual registry.

Functions

• lock 🔒
  See PackageRegistry::lock.
• summary_for_patch 🔒
  A helper for selecting the summary, or generating a helpful error message.

Type Aliases

• LockedMap 🔒
  A map of all “locked packages” which is filled in when parsing a lock file and is used to guide dependency resolution by altering summaries as they’re queried from this source.
• PatchDependency
  This tuple is an argument to PackageRegistry::patch.
