41//! **NOTE:** The scheduled calls will be dispatched with the default filter48//! **NOTE:** The unique scheduler is designed for deferred transaction calls by block number.
42//! for the origin: namely `frame_system::Config::BaseCallFilter` for all origin49//! Any user can book a call of a certain transaction to a specific block number.
43//! except root which will get no filter. And not the filter contained in origin50//! Also possible to book a call with a certain frequency.

45//!51//!
46//! If a call is scheduled using proxy or whatever mecanism which adds filter,52//! Key differences from the original pallet:
47//! then those filter will not be used when dispatching the schedule call.53//! https://crates.io/crates/pallet-scheduler
54//! Schedule Id restricted by 16 bytes. Identificator for booked call.
55//! Priority limited by HARD DEADLINE (<= 63). Calls over maximum weight don't include to block.
56//! The maximum weight that may be scheduled per block for any dispatchables of less priority than `schedule::HARD_DEADLINE`.
57//! Maybe_periodic limit is 100 calls. Reserved for future sponsored transaction support.
58//! At 100 calls reserved amount is not so much and this is avoid potential problems with balance locks.
59//! Any account allowed to schedule any calls. Account withdraw implemented through default transaction logic.
