Expand description

Represents a fully-resolved package dependency graph. Each node in the graph is a package and edges represent dependencies between packages.

Each instance of Resolve also understands the full set of features used for each package.

Fields§

§graph: Graph<PackageId, HashSet<Dependency>>

A graph, whose vertices are packages and edges are dependency specifications from Cargo.toml. We need a HashSet here because the same package might be present in both [dependencies] and [build-dependencies].

§replacements: HashMap<PackageId, PackageId>

Replacements from the [replace] table.

§reverse_replacements: HashMap<PackageId, PackageId>

Inverted version of replacements.

§features: HashMap<PackageId, Vec<InternedString>>

Features enabled for a given package.

§checksums: HashMap<PackageId, Option<String>>

Checksum for each package. A SHA256 hash of the .crate file used to validate the correct crate file is used. This is None for sources that do not use .crate files, like path or git dependencies.

§metadata: Metadata

“Unknown” metadata. This is a collection of extra, unrecognized data found in the [metadata] section of Cargo.lock, preserved for forwards compatibility.

§unused_patches: Vec<PackageId>

[patch] entries that did not match anything, preserved in Cargo.lock as the [[patch.unused]] table array. Tracking unused patches helps prevent Cargo from being forced to re-update the registry every time it runs, and keeps the resolve in a locked state so it doesn’t re-resolve the unused entries.

§public_dependencies: HashMap<PackageId, HashSet<PackageId>>

A map from packages to a set of their public dependencies

§version: ResolveVersion

Version of the Cargo.lock format, see cargo::core::resolver::encode for more.

§summaries: HashMap<PackageId, Summary>
