Expand description

Error codes used in XCM. The first errors codes have explicit indices and are part of the XCM format. Those trailing are merely part of the XCM implementation; there is no expectation that they will retain the same index over time.

Variants§

§

Overflow

An arithmetic overflow happened.

§

Unimplemented

The instruction is intentionally unsupported.

§

UntrustedReserveLocation

Origin Register does not contain a value value for a reserve transfer notification.

§

UntrustedTeleportLocation

Origin Register does not contain a value value for a teleport notification.

§

LocationFull

MultiLocation value too large to descend further.

§

LocationNotInvertible

MultiLocation value ascend more parents than known ancestors of local location.

§

BadOrigin

The Origin Register does not contain a valid value for instruction.

§

InvalidLocation

The location parameter is not a valid value for the instruction.

§

AssetNotFound

The given asset is not handled.

§

FailedToTransactAsset(&'static str)

An asset transaction (like withdraw or deposit) failed (typically due to type conversions).

§

NotWithdrawable

An asset cannot be withdrawn, potentially due to lack of ownership, availability or rights.

§

LocationCannotHold

An asset cannot be deposited under the ownership of a particular location.

§

ExceedsMaxMessageSize

Attempt to send a message greater than the maximum supported by the transport protocol.

§

DestinationUnsupported

The given message cannot be translated into a format supported by the destination.

§

Transport(&'static str)

Destination is routable, but there is some issue with the transport mechanism.

§

Unroutable

Destination is known to be unroutable.

§

UnknownClaim

Used by ClaimAsset when the given claim could not be recognized/found.

§

FailedToDecode

Used by Transact when the functor cannot be decoded.

§

MaxWeightInvalid

Used by Transact to indicate that the given weight limit could be breached by the functor.

§

NotHoldingFees

Used by BuyExecution when the Holding Register does not contain payable fees.

§

TooExpensive

Used by BuyExecution when the fees declared to purchase weight are insufficient.

§

Trap(u64)

Used by the Trap instruction to force an error intentionally. Its code is included.

§

ExpectationFalse

Used by ExpectAsset, ExpectError and ExpectOrigin when the expectation was not true.

§

PalletNotFound

The provided pallet index was not found.

§

NameMismatch

The given pallet’s name is different to that expected.

§

VersionIncompatible

The given pallet’s version has an incompatible version to that expected.

§

HoldingWouldOverflow

The given operation would lead to an overflow of the Holding Register.

§

ExportError

The message was unable to be exported.

§

ReanchorFailed

MultiLocation value failed to be reanchored.

§

NoDeal

No deal is possible under the given constraints.

§

FeesNotMet

Fees were required which the origin could not pay.

§

LockError

Some other error with locking.

§

NoPermission

The state was not in a condition where the operation was valid to make.

§

Unanchored

The universal location of the local consensus is improper.

§

NotDepositable

An asset cannot be deposited, probably because (too much of) it already exists.

§

UnhandledXcmVersion

XCM version not able to be handled.

§

WeightLimitReached(Weight)

Execution of the XCM would potentially result in a greater weight used than weight limit.

§

Barrier

The XCM did not pass the barrier condition for execution.

The barrier condition differs on different chains and in different circumstances, but generally it means that the conditions surrounding the message were not such that the chain considers the message worth spending time executing. Since most chains lift the barrier to execution on appropriate payment, presentation of an NFT voucher, or based on the message origin, it means that none of those were the case.

§

WeightNotComputable

The weight of an XCM message is not computable ahead of execution.

§

ExceedsStackLimit

Recursion stack limit reached
