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)`

`InvalidChildType`

`ExtrinsicRootInvalid`

Fields

received: String
