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.

OneShotCancelled(Canceled)

Consensus(Error)

Backend(String)

UnknownBlock(String)

ApplyExtrinsicFailed(ApplyExtrinsicFailed)
