Enum frontier_template_runtime::TimestampCall

pub enum TimestampCall<T>
where
    T: Config,
{
    set {
        now: <T as Config>::Moment,
    },
    // some variants omitted
}

Contains a variant per dispatchable extrinsic that this pallet has.

Variants

Fields

now: <T as Config>::Moment

Set the current time.

This call should be invoked exactly once per block. It will panic at the finalization phase, if this call hasn’t been invoked by that time.

The timestamp should be greater than the previous one by the amount specified by [Config::MinimumPeriod].

The dispatch origin for this call must be None.

This dispatch class is Mandatory to ensure it gets executed in the block. Be aware that changing the complexity of this call could result exhausting the resources in a block to execute any other calls.

Complexity

• O(1) (Note that implementations of OnTimestampSet must also be O(1))
• 1 storage read and 1 storage mutation (codec O(1) because of DidUpdate::take in on_finalize)
• 1 event handler on_timestamp_set. Must be O(1).
