Struct cumulus_pallet_xcmp_queue::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn service_overweight( origin: OriginFor<T>, index: OverweightIndex, weight_limit: Weight ) -> DispatchResultWithPostInfo

Services a single overweight XCM.

origin: Must pass ExecuteOverweightOrigin.
index: The index of the overweight XCM to service
weight_limit: The amount of weight that XCM execution may take.

Errors:

BadOverweightIndex: XCM under index is not found in the Overweight storage map.
BadXcm: XCM under index cannot be properly decoded into a valid XCM format.
WeightOverLimit: XCM execution may use greater weight_limit.

Events:

OverweightServiced: On success.

pub fn suspend_xcm_execution(origin: OriginFor<T>) -> DispatchResult

Suspends all XCM executions for the XCMP queue, regardless of the sender’s origin.

origin: Must pass ControllerOrigin.

pub fn resume_xcm_execution(origin: OriginFor<T>) -> DispatchResult

Resumes all XCM executions for the XCMP queue.

Note that this function doesn’t change the status of the in/out bound channels.

origin: Must pass ControllerOrigin.

pub fn update_suspend_threshold( origin: OriginFor<T>, new: u32 ) -> DispatchResult

Overwrites the number of pages of messages which must be in the queue for the other side to be told to suspend their sending.

origin: Must pass Root.
new: Desired value for QueueConfigData.suspend_value

pub fn update_drop_threshold(origin: OriginFor<T>, new: u32) -> DispatchResult

Overwrites the number of pages of messages which must be in the queue after which we drop any further messages from the channel.

origin: Must pass Root.
new: Desired value for QueueConfigData.drop_threshold

pub fn update_resume_threshold(origin: OriginFor<T>, new: u32) -> DispatchResult

Overwrites the number of pages of messages which the queue must be reduced to before it signals that message sending may recommence after it has been suspended.

origin: Must pass Root.
new: Desired value for QueueConfigData.resume_threshold

pub fn update_threshold_weight( origin: OriginFor<T>, new: Weight ) -> DispatchResult

Overwrites the amount of remaining weight under which we stop processing messages.

origin: Must pass Root.
new: Desired value for QueueConfigData.threshold_weight

pub fn update_weight_restrict_decay( origin: OriginFor<T>, new: Weight ) -> DispatchResult

Overwrites the speed to which the available weight approaches the maximum weight. A lower number results in a faster progression. A value of 1 makes the entire weight available initially.

origin: Must pass Root.
new: Desired value for QueueConfigData.weight_restrict_decay.

pub fn update_xcmp_max_individual_weight( origin: OriginFor<T>, new: Weight ) -> DispatchResult

Overwrite the maximum amount of weight any individual message may consume. Messages above this weight go into the overweight queue and may only be serviced explicitly.

origin: Must pass Root.
new: Desired value for QueueConfigData.xcmp_max_individual_weight.
