Sourcepub fn batch(&self, calls: Calls) -> StaticPayload<Batch>
pub fn batch(&self, calls: Calls) -> StaticPayload<Batch>
Send a batch of dispatch calls.
May be called from any origin except None.
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 the calls are dispatched 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.
Sourcepub fn as_derivative(
&self,
index: Index,
call: Call,
) -> StaticPayload<AsDerivative>
pub fn as_derivative( &self, index: Index, call: Call, ) -> StaticPayload<AsDerivative>
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.
Sourcepub fn batch_all(&self, calls: Calls) -> StaticPayload<BatchAll>
pub fn batch_all(&self, calls: Calls) -> StaticPayload<BatchAll>
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 except None.
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 the calls are dispatched without checking origin filter. (This
includes bypassing frame_system::Config::BaseCallFilter).
§Complexity
- O(C) where C is the number of calls to be batched.
Sourcepub fn dispatch_as(
&self,
as_origin: AsOrigin,
call: Call,
) -> StaticPayload<DispatchAs>
pub fn dispatch_as( &self, as_origin: AsOrigin, call: Call, ) -> StaticPayload<DispatchAs>
Dispatches a function call with a provided origin.
The dispatch origin for this call must be Root.
§Complexity
- O(1).
Sourcepub fn force_batch(&self, calls: Calls) -> StaticPayload<ForceBatch>
pub fn force_batch(&self, calls: Calls) -> StaticPayload<ForceBatch>
Send a batch of dispatch calls.
Unlike batch, it allows errors and won’t interrupt.
May be called from any origin except None.
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 the calls 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.
Sourcepub fn with_weight(
&self,
call: Call,
weight: Weight,
) -> StaticPayload<WithWeight>
pub fn with_weight( &self, call: Call, weight: Weight, ) -> StaticPayload<WithWeight>
Dispatch a function call with a specified weight.
This function does not check the weight of the call, and instead allows the Root origin to specify the weight of the call.
The dispatch origin for this call must be Root.
Sourcepub fn if_else(&self, main: Main, fallback: Fallback) -> StaticPayload<IfElse>
pub fn if_else(&self, main: Main, fallback: Fallback) -> StaticPayload<IfElse>
Dispatch a fallback call in the event the main call fails to execute.
May be called from any origin except None.
This function first attempts to dispatch the main call.
If the main call fails, the fallback is attemted.
if the fallback is successfully dispatched, the weights of both calls
are accumulated and an event containing the main call error is deposited.
In the event of a fallback failure the whole call fails with the weights returned.
main: The main call to be dispatched. This is the primary action to execute.fallback: The fallback call to be dispatched in case themaincall fails.
§Dispatch Logic
- If the origin is
root, both the main and fallback calls are executed without applying any origin filters. - If the origin is not
root, the origin filter is applied to both themainandfallbackcalls.
§Use Case
- Some use cases might involve submitting a
batchtype call in either main, fallback or both.
Sourcepub fn dispatch_as_fallible(
&self,
as_origin: AsOrigin,
call: Call,
) -> StaticPayload<DispatchAsFallible>
pub fn dispatch_as_fallible( &self, as_origin: AsOrigin, call: Call, ) -> StaticPayload<DispatchAsFallible>
Dispatches a function call with a provided origin.
Almost the same as [Pallet::dispatch_as] but forwards any error of the inner call.
The dispatch origin for this call must be Root.
