Function cmp_id

nodedb/src/control/planner/descriptor_set.rs:103–105

Total-order comparison for `DescriptorId` since the cluster type does not derive `Ord` (only `Hash + Eq`). We define our own by `(kind discriminant, tenant_id, name)`.

(a: &DescriptorId, b: &DescriptorId)

/// type does not derive `Ord` (only `Hash + Eq`). We define our
/// own by `(kind discriminant, tenant_id, name)`.
fn cmp_id(a: &DescriptorId, b: &DescriptorId) -> std::cmp::Ordering {
    (a.kind as u8, a.tenant_id, &a.name).cmp(&(b.kind as u8, b.tenant_id, &b.name))
}
