pub enum Step<'a, N: Node> {
Resolved(&'a N),
Unresolved(&'a N::DependencyType),
}Expand description
Wrapper around dependency graph nodes. Since a graph might have dependencies that cannot be resolved internally, this wrapper is necessary to differentiate between internally resolved and externally (unresolved) dependencies. An Unresolved dependency does not necessarily mean that it cannot be resolved, only that no Node within the graph fulfills it.
Variants§
Resolved(&'a N)
Unresolved(&'a N::DependencyType)
