The Common pallet provides an interface for common collection operations for different collection types24//! (see [CommonCollectionOperations]), as well as a generic dispatcher for these, see [dispatch] module.25//! It also provides this functionality to EVM, see [erc] and [eth] modules.26//!27//! The Common pallet provides functions for:28//!29//! - Setting and approving collection sponsor.30//! - Get\set\delete allow list.31//! - Get\set\delete collection properties.32//! - Get\set\delete collection property permissions.33//! - Get\set\delete token property permissions.34//! - Get\set\delete collection administrators.35//! - Checking access permissions.36//!37//! ### Terminology38//! **Collection sponsor** - For the collection, you can set a sponsor, at whose expense it will39//! be possible to mint tokens.40//!41//! **Allow list** - List of users who have the right to minting tokens.42//!43//! **Collection properties** - Collection properties are simply key-value stores where various44//! metadata can be placed.45//!46//! **Permissions on token properties** - For each property in the token can be set permission47//! to change, see [`PropertyPermission`].48//!49//! **Collection administrator** - For a collection, you can set administrators who have the right50//! to most actions on the collection.5152#![warn(missing_docs)]53#![cfg_attr(not(feature = "std"), no_std)]54extern crate alloc;5556use core::ops::{Deref, DerefMut};57use
