Struct parachain_piece::SetParachainInfo

pub struct SetParachainInfo<T>(/* private fields */);

A constraint checker for the simple act of including new parachain information.

This is expected to be performed through an inherent, and to happen exactly once per block.

This transaction comsumes a single input which is the previous parachain info, And it creates a new output which is the current parachain info.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T> Default for SetParachainInfo<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for SetParachainInfo<T>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> Encode for SetParachainInfo<T>

where PhantomData<T>: Encode,

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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback ) -> __CodecOutputReturn

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: ParachainPieceConfig + 'static> InherentHooks for SetParachainInfo<T>

type Error = MakeFatalError<()>

const INHERENT_IDENTIFIER: InherentIdentifier = INHERENT_IDENTIFIER

fn create_inherent<V: Verifier>( authoring_inherent_data: &InherentData, (_previous_inherent, previous_id): (Transaction<V, Self>, H256) ) -> Transaction<V, Self>

Create the inherent extrinsic to insert into a block that is being authored locally. The inherent data is supplied by the authoring node.

fn check_inherent<V>( _importing_inherent_data: &InherentData, _inherent: Transaction<V, Self>, _result: &mut CheckInherentsResult )

Perform off-chain pre-execution checks on the inherent. The inherent data is supplied by the importing node. The inherent data available here is not guaranteed to be the same as what is available at authoring time.

fn genesis_transactions<V: Verifier>() -> Vec<Transaction<V, Self>>

Return the genesis transactions that are required for this inherent.

impl<T: PartialEq> PartialEq for SetParachainInfo<T>

fn eq(&self, other: &SetParachainInfo<T>) -> 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<T> Serialize for SetParachainInfo<T>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

type Error = ParachainError

The error type that this constraint checker may return

fn check( &self, input_data: &[DynamicallyTypedData], evicted_input_data: &[DynamicallyTypedData], _peek_data: &[DynamicallyTypedData], output_data: &[DynamicallyTypedData] ) -> Result<TransactionPriority, Self::Error>

The on chain logic that makes the final check for whether a transaction is valid.

impl<T> TypeInfo for SetParachainInfo<T>

where PhantomData<T>: TypeInfo + 'static, T: 'static,

type Identity = SetParachainInfo<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
