title: Tasks API - A general system for recognizing and executing service work
|

doc:

|
|
description: |
|
|
The Tasks API allows you to define some service work that can be recognized by a script or an off-chain worker.
|
|
Such a script can then create and submit all such work items at any given time.
|
|
`#[pallet:tasks_experimental]` provides a convenient way to define such work items. It can be attached to an
|
|
`impl` block inside a pallet, whose functions can then be annotated by the following attributes:
|
|
1. `#[pallet::task_list]`: Define an iterator over the available work items for a task
|
|
2. `#[pallet::task_condition]`: Define the conditions for a given work item to be valid
|
|
3. `#[pallet::task_weight]`: Define the weight of a given work item
|
|
4. `#[pallet::task_index]`: Define the index of a given work item
|
|
Each such function becomes a variant of the autogenerated enum `Task<T>` for this pallet.
|
|
All such enums are aggregated into a `RuntimeTask` by `construct_runtime`.
|
|
An example pallet that uses the Tasks API is available at `substrate/frame/example/tasks`.
