Implementations

impl<T> Pallet<T>

where T: Config,

pub fn suspend_xcm_execution( origin: <T as Config>::RuntimeOrigin, ) -> Result<(), DispatchError>

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

• origin: Must pass ControllerOrigin.

pub fn resume_xcm_execution( origin: <T as Config>::RuntimeOrigin, ) -> Result<(), DispatchError>

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: <T as Config>::RuntimeOrigin, new: u32, ) -> Result<(), DispatchError>

Overwrites the number of pages 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: <T as Config>::RuntimeOrigin, new: u32, ) -> Result<(), DispatchError>

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

pub fn update_resume_threshold( origin: <T as Config>::RuntimeOrigin, new: u32, ) -> Result<(), DispatchError>
