Implementations

impl<T: Config> Pallet<T>
sourcepub fn set_validation_data(
origin: OriginFor<T>,
data: ParachainInherentData
) -> DispatchResultWithPostInfo
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.

origin: OriginFor<T>,

In case of a scheduled upgrade, this storage field contains the validation code to be applied.
As soon as the relay chain gives us the go-ahead signal, we will overwrite the :code
which will result the next block process with the new validation code. This concludes the upgrade process.
sourceimpl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn validation_data() -> Option<PersistedValidationData>
pub fn validation_data() -> Option<PersistedValidationData>
The [PersistedValidationData
] set for this block.
This value is expected to be set only once per block and it’s never stored
in the trie.
sourceimpl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn relay_state_proof() -> Option<StorageProof>
pub fn relay_state_proof() -> Option<StorageProof>
The state proof for the last relay parent block.
This field is meant to be updated each block with the validation data inherent. Therefore,
before processing of the inherent, e.g. in on_initialize
this data may be stale.
This data is also absent from the genesis.
sourceimpl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn relevant_messaging_state() -> Option<MessagingStateSnapshot>
pub fn relevant_messaging_state() -> Option<MessagingStateSnapshot>
The snapshot of some state related to messaging relevant to the current parachain as per the relay parent.
This field is meant to be updated each block with the validation data inherent. Therefore,
before processing of the inherent, e.g. in on_initialize
this data may be stale.
This data is also absent from the genesis.
sourceimpl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn host_configuration() -> Option<AbridgedHostConfiguration>
pub fn host_configuration() -> Option<AbridgedHostConfiguration>
The parachain host configuration that was obtained from the relay parent.
This field is meant to be updated each block with the validation data inherent. Therefore,
before processing of the inherent, e.g. in on_initialize
this data may be stale.
This data is also absent from the genesis.
sourceimpl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn max_code_size() -> Option<u32>
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.
sourcepub fn schedule_code_upgrade(validation_function: Vec<u8>) -> DispatchResult
pub fn schedule_code_upgrade(validation_function: Vec<u8>) -> DispatchResult
The implementation of the runtime upgrade functionality for parachains.
sourcepub fn collect_collation_info(header: &T::Header) -> CollationInfo
pub fn collect_collation_info(header: &T::Header) -> 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.
sourcepub fn set_custom_validation_head_data(head_data: Vec<u8>)
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.
