The Error enum of this pallet.

Variants

TooManyCandidates

The pallet has too many candidates.

TooFewEligibleCollators

Leaving would result in too few candidates.

AlreadyCandidate

Account is already a candidate.

NotCandidate

Account is not a candidate.

TooManyInvulnerables

There are too many Invulnerables.

AlreadyInvulnerable

Account is already an Invulnerable.

NotInvulnerable

Account is not an Invulnerable.

NoAssociatedValidatorId

Account has no associated validator ID.

ValidatorNotRegistered

Validator ID is not yet registered.

InsertToCandidateListFailed

Could not insert in the candidate list.

RemoveFromCandidateListFailed

Could not remove from the candidate list.

DepositTooLow

New deposit amount would be below the minimum candidacy bond.

UpdateCandidateListFailed

Could not update the candidate list.

InsufficientBond

Deposit amount is too low to take the target’s slot in the candidate list.

TargetIsNotCandidate

The target account to be replaced in the candidate list is not a candidate.

IdenticalDeposit

The updated deposit amount is equal to the amount already reserved.

InvalidUnreserve

Cannot lower candidacy bond while occupying a future collator slot in the list.
