Fields§

§age: usize§activations: HashMap<(InternedString, SourceId, SemverCompatibility), (Summary, usize)>§resolve_features: HashMap<PackageId, Rc<BTreeSet<InternedString>>>

list the features that are activated for each package

§links: HashMap<InternedString, PackageId>

get the package that will be linking to a native library by its links attribute

§public_dependency: Option<PublicDependency>

for each package the list of names it can see, then for each name the exact version that name represents and whether the name is public.

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

a way to look up for a package in activations what packages required it and all of the exact deps that it fulfilled.

Implementations§

Activate this summary by inserting it into our list of known activations.

The parent passed in here is the parent summary/dependency edge which cased summary to get activated. This may not be present for the root crate, for example.

Returns true if this summary with the given features is already activated.

If the package is active returns the ContextAge when it was added

If the conflict reason on the package still applies returns the ContextAge when it was added

Checks whether all of parent and the keys of conflicting activations are still active. If so returns the ContextAge when the newest one was added.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
