Expand description

Reason an append failed.

Variants (Non-exhaustive)

This enum is marked as 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.

`Converged`

Fields

caught_up: bool

Whether this node has already learned the converged on value for this round.

The chosen round had already converged.

`Disoriented`

Node does not currently know the shared state.

`Exiled`

Node was removed from the cluster.

`Lost`

Node either lost its mandate or failed in acquiring one.

`NoQuorum`

Fields

abstentions: Vec<AbstainOf<I>>

All abstentions received.

communication_errors: Vec<CommunicationErrorOf<I>>

All encountered errors.

rejections: Vec<NayOf<I>>

All rejections received.

Failed in achieving a quorum.

`Decoration(Box<dyn Error + Send + Sync + 'static>)`

Catch-all, this may be refined over time.

`Passive`

Node is in passive mode.

`Railroaded`

Node was forced to append a different entry for the chosen round.

`ShutDown`

Node is shut down.
