#[doc = r"The `pallet` module in each FRAME pallet hosts the most important items needed
to construct this pallet.
The main components of this pallet are:
- [`Pallet`], which implements all of the dispatchable extrinsics of the pallet, among
other public functions.
- The subset of the functions that are dispatchable can be identified either in the
[`dispatchables`] module or in the [`Call`] enum.
- [`storage_types`], which contains the list of all types that are representing a
storage item. Otherwise, all storage items are listed among [*Type Definitions*](#types).
- [`Config`], which contains the configuration trait of this pallet.
- [`Event`] and [`Error`], which are listed among the [*Enums*](#enums).
