Comparable interface

As explained in Classic Computer Science Problems in Swift: Essential techniques for practicing programmers

Comparable is a Swift standard-library protocol for types whose values can be ordered relative to one another.

How Classic Computer Science Problems in Swift: Essential techniques for practicing programmers covers it

How deep it goes

Defines comparison for a concrete generic Node type but does not survey Comparable requirements beyond the shown operators.

Examples

Uses a generic Node whose < operator compares cost plus heuristic and whose == operator compares reference identity.

What it assumes

Assumes familiarity with generic types, Node values, cost, heuristic, and Hashable conformance.

What you can do after

Apply it via Swift operator overloads to rank custom search nodes for priority-based algorithms.

How it connects

Connects Node, Hashable, A*, priority queues, cost, and heuristic values.
