Scheduler

A module for scheduling dispatches.

• scheduler::Config
• Call
• Module

Overview

This module exposes capabilities for scheduling dispatches to occur at a specified block number or at a specified period. These scheduled dispatches may be named or anonymous and may be canceled.

NOTE: The scheduled calls will be dispatched with the default filter for the origin: namely frame_system::Config::BaseCallFilter for all origin except root which will get no filter. And not the filter contained in origin use to call fn schedule.

If a call is scheduled using proxy or whatever mechanism which adds filter, then those filter will not be used when dispatching the schedule call.
