Version 1 payloads for MessageToPara.

Variants

RegisterResponse

Report how a registration requested with MessageToRelayV1::Register ended.

para_id correlates the response with its request: a parachain only sends MessageToRelayV1::Register for a para id that is reserved and otherwise idle, so at most one request per para id is ever in flight. message_id echoes the request’s id on top, tying the two together across chains and in events.

Fields

para_id: ParaId

The para id the report is about.

message_id: u64

The id of the MessageToRelayV1::Register this answers, echoed back.

outcome: Outcome

Whether the registration was applied on the relay chain.

CancelResponse

Answer a MessageToRelayV1::CancelRegistration.

Ok(()) means the relay chain is no longer holding an authorization for this para id, so the deposit can be released. The only refusal is FailureReason::AlreadyRegistered: the code did land after all and the para is registered, so the deposit stays where it is.

Fields

para_id: ParaId

The para id the answer is about.

message_id: u64

The id of the MessageToRelayV1::CancelRegistration this answers, echoed back.

outcome: Outcome

Whether the authorization was dropped.

Trait Implementations

impl Clone for MessageToParaV1

fn clone(&self) -> MessageToParaV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageToParaV1

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

Formats the value using the given formatter.

impl Decode for MessageToParaV1

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

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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 Encode for MessageToParaV1

fn size_hint(&self) -> usize

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

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

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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 MaxEncodedLen for MessageToParaV1

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq for MessageToParaV1

fn eq(&self, other: &MessageToParaV1) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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