pub enum ConflictResolution {
Exact(SequenceNumber, ObjectID),
AtLeast(SequenceNumber, ObjectID),
}
Expand description
Unifiers. These are used to determine how to unify two packages.
Variants§
Exact(SequenceNumber, ObjectID)
An exact constraint unifies as follows:
- Exact(a) ~ Exact(b) ==> Exact(a), iff a == b
- Exact(a) ~ AtLeast(b) ==> Exact(a), iff a >= b
AtLeast(SequenceNumber, ObjectID)
An at least constraint unifies as follows:
- AtLeast(a, a_version) ~ AtLeast(b, b_version) ==> AtLeast(x, max(a_version, b_version)), where x is the package id of either a or b (the one with the greatest version).
