Expand description
The Pallet
struct, the main type that implements traits and standalone
functions within the pallet.
Implementations§
source§impl<T: Config> Pallet<T>
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.
pub fn sudo_send_upward_message( origin: OriginFor<T>, message: UpwardMessage, ) -> DispatchResult
source§impl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn unincluded_segment_size_after(included_hash: T::Hash) -> u32
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.
source§impl<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: &HeaderFor<T>) -> CollationInfo
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.
sourcepub fn core_selector() -> (CoreSelector, ClaimQueueOffset)
pub fn core_selector() -> (CoreSelector, ClaimQueueOffset)
Returns the core selector for the next block.
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.
sourcepub fn open_outbound_hrmp_channel_for_benchmarks_or_tests(
target_parachain: ParaId,
)
pub fn open_outbound_hrmp_channel_for_benchmarks_or_tests( target_parachain: ParaId, )
Open HRMP channel for using it in benchmarks or tests.
The caller assumes that the pallet will accept regular outbound message to the sibling
target_parachain
after this call. No other assumptions are made.
sourcepub fn open_custom_outbound_hrmp_channel_for_benchmarks_or_tests(
target_parachain: ParaId,
channel: AbridgedHrmpChannel,
)
pub fn open_custom_outbound_hrmp_channel_for_benchmarks_or_tests( target_parachain: ParaId, channel: AbridgedHrmpChannel, )
Open HRMP channel for using it in benchmarks or tests.
The caller assumes that the pallet will accept regular outbound message to the sibling
target_parachain
after this call. No other assumptions are made.
sourcepub fn initialize_for_set_code_benchmark(max_code_size: u32)
pub fn initialize_for_set_code_benchmark(max_code_size: u32)
Prepare/insert relevant data for schedule_code_upgrade
for benchmarks.
source§impl<T: Config> Pallet<T>
impl<T: Config> Pallet<T>
sourcepub fn send_upward_message(
message: UpwardMessage,
) -> Result<(u32, XcmHash), MessageSendError>
pub fn send_upward_message( message: UpwardMessage, ) -> Result<(u32, XcmHash), MessageSendError>
Puts a message in the PendingUpwardMessages
storage item.
The message will be later sent in on_finalize
.
Checks host configuration to see if message is too big.
Increases the delivery fee factor if the queue is sufficiently (see
ump_constants::THRESHOLD_FACTOR
) congested.
sourcepub fn last_relay_block_number() -> RelayChainBlockNumber
pub fn last_relay_block_number() -> RelayChainBlockNumber
Get the relay chain block number which was used as an anchor for the last block in this chain.

total size is less than the threshold (see ump_constants::THRESHOLD_FACTOR
).
Also does the sending for HRMP messages it takes from OutboundXcmpMessageSource
