In dependency resolution, these are derived from version requirements and when running into unresolvable situations.
struct TermA term represents a statement about a package that may be true or false.
enum DependencyResolutionNodeA node in the dependency resolution graph.
indirect enum CauseEvery incompatibility has a cause to explain its presence in the derivation graph. Only the root incompatibility uses .root. All other incompatibilities are either obtained from dependency constraints, decided upon in decision making or derived during unit propagation or conflict resolution. Using this information we can build up a derivation graph by following the tree of causes. All leaf nodes are external dependencies and all internal nodes are derived incompatibilities.
