Incompatibility
A set of terms that are incompatible with each other and can therefore not all be true at the same time. In dependency resolution, these are derived from version requirements and when running into unresolvable situations.

Conformances
protocol CopyableA type whose values can be implicitly or explicitly copied.
protocol CustomStringConvertibleA type with a customized textual representation.
protocol EquatableA type that can be compared for value equality.
protocol Escapableprotocol HashableA type that can be hashed into a
Hasherto produce an integer hash value.
Types
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.
