• function trap(struct TrapErrorParams params) internal pure returns (struct XcmError)

unit(struct UnitParams params)

function unit(struct UnitParams params) internal pure returns (struct XcmError)

Creates a unit `XcmError` with no payload.

trap(struct TrapErrorParams params)

function trap(struct TrapErrorParams params) internal pure returns (struct XcmError)

Creates a `Trap` error with the given u64 code.

File-Level Structs

• XcmError

• UnitParams

• TrapErrorParams

XcmError

struct XcmError

XCM v5 error, containing the error type and an optional payload for `Trap`.

Field	Type	Description
variant	XcmErrorVariant	The type of the error. See `XcmErrorVariant` enum for possible values.
payload	bytes	The trap code. Only meaningful when `variant` is `Trap`.

UnitParams

struct UnitParams

Parameters for unit (payload-less) XCM errors.

Field	Type	Description
variant	XcmErrorVariant	The non-trap error discriminant.

TrapErrorParams

struct TrapErrorParams

Parameters for the `Trap` error variant.

Field	Type	Description
code	uint64	Trap code.

File-Level Enums

• XcmErrorVariant

XcmErrorVariant

enum XcmErrorVariant

Error codes used in XCM.

Variant	Description
Overflow	An arithmetic overflow happened.
Unimplemented	The instruction is intentionally unsupported.
UntrustedReserveLocation	Origin Register does not contain a valid value for a reserve transfer notification.
UntrustedTeleportLocation	Origin Register does not contain a valid value for a teleport notification.
LocationFull	`MultiLocation` value too large to descend further.
LocationNotInvertible	`MultiLocation` value ascends more parents than known ancestors of local location.
BadOrigin	The Origin Register does not contain a valid value for the instruction.
InvalidLocation	The location parameter is not a valid value for the instruction.
AssetNotFound	The given asset is not handled.
FailedToTransactAsset	An asset transaction failed, typically due to type conversions. NOTE: The string field is #[codec(skip)] and not serialized.
NotWithdrawable	An asset cannot be withdrawn, potentially due to lack of ownership, availability or rights.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	Destination is routable, but there is some issue with the transport mechanism. NOTE: The string field is #[codec(skip)] and not serialized.
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	Used by the `Trap` instruction to force an error intentionally.
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.
TooManyAssets	Too many assets matched the given asset filter.
