Struct cumulus_pallet_parachain_system::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn set_validation_data( origin: OriginFor<T>, data: ParachainInherentData ) -> DispatchResultWithPostInfo

Set the current validation data.

This should be invoked exactly once per block. It will panic at the finalization phase if the call was not invoked.

The dispatch origin for this call must be Inherent

As a side effect, this function upgrades the current validation function if the appropriate time has come.

pub fn sudo_send_upward_message( origin: OriginFor<T>, message: UpwardMessage ) -> DispatchResult

pub fn authorize_upgrade( origin: OriginFor<T>, code_hash: T::Hash, check_version: bool ) -> DispatchResult

Authorize an upgrade to a given code_hash for the runtime. The runtime can be supplied later.

The check_version parameter sets a boolean flag for whether or not the runtime’s spec version and name should be verified on upgrade. Since the authorization only has a hash, it cannot actually perform the verification.

This call requires Root origin.

pub fn enact_authorized_upgrade( _: OriginFor<T>, code: Vec<u8> ) -> DispatchResultWithPostInfo

Provide the preimage (runtime binary) code for an upgrade that has been authorized.

If the authorization required a version check, this call will ensure the spec name remains unchanged and that the spec version has increased.

Note that this function will not apply the new code, but only attempt to schedule the upgrade with the Relay Chain.

All origins are allowed.

pub fn new_validation_function() -> Vec<u8> ⓘ

An auto-generated getter for PendingValidationCode.

impl<T: Config> Pallet<T>

pub fn validation_data() -> Option<PersistedValidationData>

An auto-generated getter for ValidationData.

impl<T: Config> Pallet<T>

pub fn relay_state_proof() -> Option<StorageProof>

An auto-generated getter for RelayStateProof.

impl<T: Config> Pallet<T>

pub fn relevant_messaging_state() -> Option<MessagingStateSnapshot>

An auto-generated getter for RelevantMessagingState.

impl<T: Config> Pallet<T>

pub fn host_configuration() -> Option<AbridgedHostConfiguration>

An auto-generated getter for HostConfiguration.

impl<T: Config> Pallet<T>

pub fn unincluded_segment_size_after(included_hash: T::Hash) -> u32

Get the unincluded segment size after the given hash.

If the unincluded segment doesn’t contain the given hash, this returns the length of the entire unincluded segment.

This is intended to be used for determining how long the unincluded segment would be in runtime APIs related to authoring.

impl<T: Config> Pallet<T>

pub fn max_code_size() -> Option<u32>

The maximum code size permitted, in bytes.

Returns None if the relay chain parachain host configuration hasn’t been submitted yet.

pub fn schedule_code_upgrade(validation_function: Vec<u8>) -> DispatchResult

The implementation of the runtime upgrade functionality for parachains.

pub fn collect_collation_info(header: &HeaderFor<T>) -> CollationInfo

Returns the CollationInfo of the current active block.

The given header is the header of the built block we are collecting the collation info for.

This is expected to be used by the CollectCollationInfo runtime api.

pub fn set_custom_validation_head_data(head_data: Vec<u8>)

Set a custom head data that should be returned as result of validate_block.

This will overwrite the head data that is returned as result of validate_block while validating a PoV on the relay chain. Normally the head data that is being returned by validate_block is the header of the block that is validated, thus it can be enacted as the new best block. However, for features like forking it can be useful to overwrite the head data with a custom header.

Attention

This should only be used when you are sure what you are doing as this can brick your Parachain.
