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.

Trait Implementations

impl Clone for ParachainInherentData

fn clone(&self) -> ParachainInherentData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParachainInherentData

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

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 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 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 InherentDataProvider for ParachainInherentData

fn provide_inherent_data(
    &self,
    inherent_data: &mut InherentData
) -> Result<(), Error>

Provide inherent data that should be included in a block.

fn try_handle_error<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    __arg1: &'life1 InherentIdentifier,
    __arg2: &'life2 [u8]
) -> Pin<Box<dyn Future<Output = Option<Result<(), Error>>> + Send + 'async_trait>>where
    Self: 'async_trait,

fn create_inherent_data(&self) -> Result<InherentData, Error>

Convenience function for creating InherentData.

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.

type Identity = ParachainInherentData

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
