struct Requirements<'a> {
summary: &'a Summary,
deps: HashMap<InternedString, BTreeSet<InternedString>>,
features: HashSet<InternedString>,
}
Expand description
Set of feature and dependency requirements for a package.
Fields§
§summary: &'a Summary
§deps: HashMap<InternedString, BTreeSet<InternedString>>
The deps map is a mapping of dependency name to list of features enabled.
The resolver will activate all of these dependencies, with the given features enabled.
features: HashSet<InternedString>
The set of features enabled on this package which is later used when compiling to instruct the code what features were enabled.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
