ConflictCause
Incompatibility.swift:93struct ConflictCausestruct ConflictCauseimport PackageGraphindirect 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.
struct IncompatibilityA 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.
var isConflict: Bool { get }var isSingleLine: Bool { get }Returns whether this cause can be represented in a single line of the error output.
protocol EquatableA type that can be compared for value equality.
protocol Hashable : EquatableA type that can be hashed into a Hasher to produce an integer hash value.
let conflict: Incompatibilitylet other: Incompatibilitystatic func != (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether two values are not equal.
