Implementations

impl<T: Config> Pallet<T>

pub fn reap_page( origin: OriginFor<T>, message_origin: MessageOriginOf<T>, page_index: u32, ) -> DispatchResult

Remove a page which has no more messages remaining to be processed or is stale.

pub fn execute_overweight( origin: OriginFor<T>, message_origin: MessageOriginOf<T>, page: u32, index: T::Size, weight_limit: Weight, ) -> DispatchResultWithPostInfo

Execute an overweight message.

Temporary processing errors will be propagated whereas permanent errors are treated as success condition.

• origin: Must be Signed.
• message_origin: The origin from which the message to be executed arrived.
• page: The page in the queue in which the message to be executed is sitting.
• index: The index into the queue of the message to be executed.
• weight_limit: The maximum amount of weight allowed to be consumed in the execution of the message.

Benchmark complexity considerations: O(index + weight_limit).

impl<T: Config> Pallet<T>

pub fn do_execute_overweight( origin: MessageOriginOf<T>, page_index: u32, index: T::Size, weight_limit: Weight, ) -> Result<Weight, Error<T>>

Try to execute a single message that was marked as overweight.

The weight_limit is the weight that can be consumed to execute the message. The base weight of the function it self must be measured by the caller.

pub fn do_try_state() -> Result<(), TryRuntimeError>

Ensure the correctness of state of this pallet.

Assumptions-

If serviceHead points to a ready Queue, then BookState of that Queue has:

• message_count > 0
• size > 0
• end > begin
• Some(ready_neighbours)
• If ready_neighbours.next == self.origin, then ready_neighbours.prev == self.origin (only queue in ring)

For Pages(begin to end-1) in BookState:

• remaining > 0
• remaining_size > 0
• first <= last
• Every page can be decoded into peek_* functions

pub fn debug_info() -> String

Print the pages in each queue and the messages in each page.

Processed messages are prefixed with a * and the current beginning page with a >.

Example output

queue Here:
  page 0: []
> page 1: []
  page 2: ["\0weight=4", "\0c", ]
  page 3: ["\0bigbig 1", ]
  page 4: ["\0bigbig 2", ]
  page 5: ["\0bigbig 3", ]
