Struct cumulus_primitives_parachain_inherent::ParachainInherentData

pub struct ParachainInherentData {
    pub validation_data: PersistedValidationData,
    pub relay_chain_state: StorageProof,
    pub downward_messages: Vec<InboundDownwardMessage>,
    pub horizontal_messages: BTreeMap<ParaId, Vec<InboundHrmpMessage>>,
}

The inherent data that is passed by the collator to the parachain runtime.

Fields

validation_data: PersistedValidationData

relay_chain_state: StorageProof

A storage proof of a predefined set of keys from the relay-chain.

Specifically this witness contains the data for:

• the current slot number at the given relay parent
• active host configuration as per the relay parent,
• the relay dispatch queue sizes
• the list of egress HRMP channels (in the list of recipients form)
• the metadata for the egress HRMP channels

downward_messages: Vec<InboundDownwardMessage>

Downward messages in the order they were sent.

horizontal_messages: BTreeMap<ParaId, Vec<InboundHrmpMessage>>

HRMP messages grouped by channels. The messages in the inner vec must be in order they were sent. In combination with the rule of no more than one message in a channel per block, this means sent_at is strictly greater than the previous one (if any).

Implementations

impl ParachainInherentData

pub async fn create_at( relay_parent: PHash, relay_chain_interface: &impl RelayChainInterface, validation_data: &PersistedValidationData, para_id: ParaId ) -> Option<ParachainInherentData>

Create the ParachainInherentData at the given relay_parent.

Returns None if the creation failed.

Formats the value using the given formatter.

impl Decode for ParachainInherentData

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,

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 ParachainInherentData

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, 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 InherentDataProvider for ParachainInherentData

fn provide_inherent_data<'life0, 'life1, 'async_trait>( &'life0 self, inherent_data: &'life1 mut InherentData ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Provide inherent data that should be included in a block.

fn try_handle_error<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _: &'life1 InherentIdentifier, _: &'life2 [u8] ) -> Pin<Box<dyn Future<Output = Option<Result<(), Error>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

impl PartialEq<ParachainInherentData> for ParachainInherentData

fn eq(&self, other: &ParachainInherentData) -> 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.

impl TypeInfo for ParachainInherentData

type Identity = ParachainInherentData

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
