However, the compiler enforces strict coherence rules to ensure that trait implementations remain unambiguous. Error code <strong>E0782</strong> signals that you have defined two implementations of the same trait for identical type parameters, or that your implementation conflicts with one that already exists in scope. This violates the core guarantee that at most one implementation of a trait for a given type should ever be applicable.</p>
