The Error enum of this pallet.

Variants

DelegatorNotFound

The account is not part of the delegators set.

CandidateNotFound

The account is not part of the collator candidates set.

DelegatorExists

The account is already part of the delegators set.

CandidateExists

The account is already part of the collator candidates set.

ValStakeZero

The account tried to stake more or less with amount zero.

ValStakeBelowMin

The account has not staked enough funds to be added to the collator candidates set.

ValStakeAboveMax

The account has already staked the maximum amount of funds possible.

DelegationBelowMin

The account has not staked enough funds to delegate a collator candidate.

AlreadyLeaving

The collator candidate has already trigger the process to leave the set of collator candidates.

NotLeaving

The collator candidate wanted to execute the exit but has not requested to leave before by calling init_leave_candidates.

CannotLeaveYet

The collator tried to leave before waiting at least for ExitQueueDelay many rounds.

CannotJoinBeforeUnlocking

The account has a full list of unstaking requests and needs to unlock at least one of these before being able to join (again). NOTE: Can only happen if the account was a candidate or delegator before and either got kicked or exited voluntarily.

AlreadyDelegating

The account is already delegating the collator candidate.

NotYetDelegating

The account has not delegated any collator candidate yet, hence it is not in the set of delegators.

DelegationsPerRoundExceeded

The delegator has exceeded the number of delegations per round which is equal to MaxDelegatorsPerCollator.

This protects against attacks in which a delegator can re-delegate from a collator who has already authored a block, to another one which has not in this round.

TooManyDelegators

The collator candidate has already reached the maximum number of delegators.

This error is generated in case a new delegation request does not stake enough funds to replace some other existing delegation.

TooFewCollatorCandidates

The set of collator candidates would fall below the required minimum if the collator left.

CannotStakeIfLeaving

The collator candidate is in the process of leaving the set of candidates and cannot perform any other actions in the meantime.

CannotDelegateIfLeaving

The collator candidate is in the process of leaving the set of candidates and thus cannot be delegated to.

MaxCollatorsPerDelegatorExceeded

The delegator has already delegated the maximum number of candidates allowed.

AlreadyDelegatedCollator

The delegator has already previously delegated the collator candidate.

DelegationNotFound

The given delegation does not exist in the set of delegations.

Underflow

The collator delegate or the delegator is trying to un-stake more funds that are currently staked.

CannotSetAboveMax

The number of selected candidates per staking round is above the maximum value allowed.

CannotSetBelowMin

The number of selected candidates per staking round is below the minimum value allowed.

InvalidSchedule

An invalid inflation configuration is trying to be set.

NoMoreUnstaking

The staking reward being unlocked does not exist. Max unlocking requests reached.

TooEarly

The reward rate cannot be adjusted yet as an entire year has not passed.

StakeNotFound

Provided staked value is zero. Should never be thrown.

UnstakingIsEmpty

Cannot unlock when Unstaked is empty.

RewardsNotFound

Cannot claim rewards if empty.
