Struct ProjectDependencyGraph 

pub struct ProjectDependencyGraph { /* private fields */ }

The ProjectDependencyGraph represents a materialized dependency graph rooted at a specific package.

Each node in the graph corresponds to a specific package version, and describes:

• What packages it depends on, and with what linkage
• The provenance of the package, i.e. whether the package was sourced from a pre-assembled artifact on the local filesystem; assembled from source that is present on the local filesystem (and where those sources came from); or was fetched from the package registry.

The assembler uses this dependency graph both for validation, and to ensure that all dependencies of a package are properly linked.

See ProjectDependencyGraphBuilder for more details on constructing a ProjectDependencyGraph.

Implementations

impl ProjectDependencyGraph

pub fn root(&self) -> &PackageId

Get the package identifier of the root package

pub fn nodes(&self) -> &BTreeMap<PackageId, ProjectDependencyNode>

Get the nodes of the underlying graph

pub fn get(&self, package: &PackageId) -> Option<&ProjectDependencyNode>

Get the node corresponding to package

Trait Implementations

impl Clone for ProjectDependencyGraph

fn clone(&self) -> ProjectDependencyGraph

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProjectDependencyGraph

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ProjectDependencyGraph

fn eq(&self, other: &ProjectDependencyGraph) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
