The event emitted by this pallet.

Variants

Attempted(Outcome)

Execution of an XCM message was attempted.

[ outcome ]

Sent(MultiLocation, MultiLocation, Xcm<()>)

A XCM message was sent.

[ origin, destination, message ]

UnexpectedResponse(MultiLocation, QueryId)

Query response received which does not match a registered query. This may be because a matching query was never registered, it may be because it is a duplicate response, or because the query timed out.

[ origin location, id ]

ResponseReady(QueryId, Response)

Query response has been received and is ready for taking with take_response. There is no registered notification call.

[ id, response ]

Notified(QueryId, u8, u8)

Query response has been received and query is removed. The registered notification has been dispatched and executed successfully.

[ id, pallet index, call index ]

NotifyOverweight(QueryId, u8, u8, Weight, Weight)

Query response has been received and query is removed. The registered notification could not be dispatched because the dispatch weight is greater than the maximum weight originally budgeted by this runtime for the query result.

[ id, pallet index, call index, actual weight, max budgeted weight ]

NotifyDispatchError(QueryId, u8, u8)

Query response has been received and query is removed. There was a general error with dispatching the notification call.

[ id, pallet index, call index ]

NotifyDecodeFailed(QueryId, u8, u8)

Query response has been received and query is removed. The dispatch was unable to be decoded into a Call; this might be due to dispatch function having a signature which is not (origin, QueryId, Response).

[ id, pallet index, call index ]

InvalidResponder(MultiLocation, QueryId, Option<MultiLocation>)

Expected query response has been received but the origin location of the response does not match that expected. The query remains registered for a later, valid, response to be received and acted upon.

[ origin location, id, expected location ]

InvalidResponderVersion(MultiLocation, QueryId)

Expected query response has been received but the expected origin location placed in storage by this runtime previously cannot be decoded. The query remains registered.

This is unexpected (since a location placed in storage in a previously executing runtime should be readable prior to query timeout) and dangerous since the possibly valid response will be dropped. Manual governance intervention is probably going to be needed.

[ origin location, id ]

ResponseTaken(QueryId)

Received query response has been read and removed.

[ id ]

AssetsTrapped(H256, MultiLocation, VersionedMultiAssets)

Some assets have been placed in an asset trap.

[ hash, origin, assets ]

VersionChangeNotified(MultiLocation, XcmVersion)

An XCM version change notification message has been attempted to be sent.

[ destination, result ]

SupportedVersionChanged(MultiLocation, XcmVersion)

The supported version of a location has been changed. This might be through an automatic notification or a manual intervention.

[ location, XCM version ]

NotifyTargetSendFail(MultiLocation, QueryId, XcmError)

A given location which had a version change subscription was dropped owing to an error sending the notification to it.

[ location, query ID, error ]

NotifyTargetMigrationFail(VersionedMultiLocation, QueryId)

A given location which had a version change subscription was dropped owing to an error migrating the location to our new XCM format.

[ location, query ID ]

AssetsClaimed(H256, MultiLocation, VersionedMultiAssets)

Some assets have been claimed from an asset trap

[ hash, origin, assets ]

Trait Implementations

impl<T: Config> Clone for Event<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Config> Debug for Event<T>

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Config> Decode for Event<T>

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T: Config> Encode for Event<T>

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: Config> From<Event<T>> for ()

fn from(_: Event<T>)

Converts to this type from the input type.

impl<T: Config> PartialEq<Event<T>> for Event<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

type Identity = Event<T>

The type identifying for which type info is provided.

fn type_info() -> Type
