A module for scheduling dispatches.20//!21//! - [`Config`]22//! - [`Call`]23//! - [`Module`]24//!25//! ## Overview26//!27//! This module exposes capabilities for scheduling dispatches to occur at a28//! specified block number or at a specified period. These scheduled dispatches29//! may be named or anonymous and may be canceled.30//!31//! **NOTE:** The scheduled calls will be dispatched with the default filter32//! for the origin: namely `frame_system::Config::BaseCallFilter` for all origin33//! except root which will get no filter. And not the filter contained in origin34//! use to call `fn schedule`.35//!36//! If a call is scheduled using proxy or whatever mecanism which adds filter,37//! then those filter will not be used when dispatching the schedule call.38//!39//! ## Interface40//!41//! ### Dispatchable Functions42//!43//! * `schedule` - schedule a dispatch, which may be periodic, to occur at a44//!   specified block and with a specified priority.45//! * `cancel` - cancel a scheduled dispatch, specified by block number and46//!   index.47//! * `schedule_named` - augments the `schedule` interface with an additional48//!   `Vec<u8>` parameter that can be used for identification.49//! * `cancel_named` - the named complement to the cancel function.5051// Ensure we're `no_std` when compiling for Wasm.52#![cfg_attr(not(feature = "std"), no_std)]53#![allow(clippy::type_complexity, clippy::boxed_local, clippy::unused_unit)]5455mod benchmarking;56pub mod weights;5758use sp_std::{prelude::*, marker::PhantomData, borrow::Borrow};59use codec::{Encode, Decode, Codec};60use sp_runtime::{61	RuntimeDebug,62	traits::{Zero, One, BadOrigin, Saturating},63};64use frame_support::{65	decl_module, decl_storage, decl_event, decl_error,66	dispatch::{Dispatchable, DispatchError, DispatchResult, Parameter},67	traits::{68		Get,69		schedule::{self, DispatchTime},70		OriginTrait, EnsureOrigin, IsType,71	},72	weights::{GetDispatchInfo, Weight},73};74use frame_system::{self as system, ensure_signed};75pub use weights::WeightInfo;76use up_sponsorship::SponsorshipHandler;77use scale_info::TypeInfo;7879/// Our pallet's configuration trait.
