Expand description

Errors that can happen in the feasibility check.

Variants§

WrongWinnerCount

Wrong number of winners presented.

SnapshotUnavailable

The snapshot is not available.

Kinda defensive: The pallet should technically never attempt to do a feasibility check when no snapshot is present.

NposElection(Error)

Internal error from the election crate.

InvalidVote

A vote is invalid.

InvalidVoter

A voter is invalid.

InvalidScore

The given score was invalid.

InvalidRound

The provided round is incorrect.

UntrustedScoreTooLow

Comparison against MinimumUntrustedScore failed.

TooManyDesiredTargets

Data Provider returned too many desired targets

BoundedConversionFailed

Conversion into bounded types failed.

Should never happen under correct configurations.
