The Error enum of this pallet.

Variants

BalanceLow

Account balance must be greater than or equal to the transfer amount.

NoAccount

The account to alter does not exist.

NoPermission

The signing account has no permission to do the operation.

Unknown

The given asset ID is unknown.

Frozen

The origin account is frozen.

InUse

The asset ID is already taken.

BadWitness

Invalid witness data given.

MinBalanceZero

Minimum balance should be non-zero.

UnavailableConsumer

Unable to increment the consumer reference counters on the account. Either no provider reference exists to allow a non-zero balance of a non-self-sufficient asset, or one fewer then the maximum number of consumers has been reached.

BadMetadata

Invalid metadata given.

Unapproved

No approval exists that would allow the transfer.

WouldDie

The source account would not survive the transfer and it needs to stay alive.

AlreadyExists

The asset-account already exists.

NoDeposit

The asset-account doesn’t have an associated deposit.

WouldBurn

The operation would result in funds being burned.

LiveAsset

The asset is a live asset and is actively being used. Usually emit for operations such as start_destroy which require the asset to be in a destroying state.

AssetNotLive

The asset is not live, and likely being destroyed.

IncorrectStatus

The asset status is not the expected status.

NotFrozen

The asset should be frozen before the given operation.

CallbackFailed

Callback action resulted in error

BadAssetId

The asset ID must be equal to the NextAssetId.

ContainsFreezes

The asset cannot be destroyed because some accounts for this asset contain freezes.

ContainsHolds

The asset cannot be destroyed because some accounts for this asset contain holds.
