Enum Selection 

#[non_exhaustive]
pub enum Selection<P> {
    Current(P),
    Committed,
    NotCommitted,
}

What an observer may report about a candidate it does not drive.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Current(P)

A fresh probe proved the candidate is serving.

Committed

The selection names the candidate, but no fresh probe proved it within Budget::proof. The candidate is authoritative: do not roll back, restart or select anything around it.

NotCommitted

Budget::commit passed without the selection naming the candidate.
