Struct pallet_utility::pallet::Pallet [−][src]
pub struct Pallet<T>(_);
Expand description
The pallet implementing the on-chain logic.
Implementations
Send a batch of dispatch calls.
May be called from any origin.
calls
: The calls to be dispatched from the same origin. The number of call must not exceed the constant:batched_calls_limit
(available in constant metadata).
If origin is root then call are dispatch without checking origin filter. (This includes
bypassing frame_system::Config::BaseCallFilter
).
- Complexity: O(C) where C is the number of calls to be batched.
This will return Ok
in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
BatchInterrupted
event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the BatchCompleted
event is deposited.
pub fn as_derivative(
origin: OriginFor<T>,
index: u16,
call: Box<<T as Config>::Call>
) -> DispatchResultWithPostInfo
pub fn as_derivative(
origin: OriginFor<T>,
index: u16,
call: Box<<T as Config>::Call>
) -> DispatchResultWithPostInfo
Send a call through an indexed pseudonym of the sender.
Filter from origin are passed along. The call will be dispatched with an origin which use the same filter as the origin of this call.
NOTE: If you need to ensure that any account-based filtering is not honored (i.e.
because you expect proxy
to have been used prior in the call stack and you do not want
the call restrictions to apply to any sub-accounts), then use as_multi_threshold_1
in the Multisig pallet instead.
NOTE: Prior to version *12, this was called as_limited_sub
.
The dispatch origin for this call must be Signed.
Send a batch of dispatch calls and atomically execute them. The whole transaction will rollback and fail if any of the calls failed.
May be called from any origin.

pub fn dispatch_as(

Derive a derivative account ID from the owner account and the sub-account index.

The block is being finalized. Implement to have something happen.
This will be run when the block is being finalized (before on_finalize
).
Implement to have something happen using the remaining weight.
Will not fire if the remaining weight is 0.
Return the weight used, the hook will subtract it from current weight used
and pass the result to the next on_idle
hook if it exists. Read more

Something that should happen at genesis.

Implement to have something happen in case there is leftover weight.
Check the passed remaining_weight
to make sure it is high enough to allow for
your pallet’s extra computation. Read more
