The Common pallet provides functions for:24//! 25//! - Setting and approving collection soponsor.26//! - Get\set\delete allow list.27//! - Get\set\delete collection properties.28//! - Get\set\delete collection property permissions.29//! - Get\set\delete token property permissions.30//! - Get\set\delete collection administrators.31//! - Checking access permissions.32//! - Provides an interface for common collection operations for different collection types.33//! - Provides dispatching for implementations of common collection operations, see [dispatch] module.34//! - Provides functionality of collection into evm, see [erc] and [eth] module.35//! 36//! ### Terminology37//! **Collection sponsor** - For the collection, you can set a sponsor, at whose expense it will 38//! be possible to mint tokens.39//! 40//! **Allow list** - List of users who have the right to minting tokens.41//! 42//! **Collection properties** - Collection properties are simply key-value stores where various 43//! metadata can be placed.44//! 45//! **Collection property permissions** - For each property in the collection can be set permission 46//! to change, see [PropertyPermission].47//! 48//! **Permissions on token properties** - Similar to _permissions on collection properties_, 49//! only restrictions apply to token properties.50//! 51//! **Collection administrator** - For a collection, you can set administrators who have the right 52//! to most actions on the collection.535455#![warn(missing_docs)]56#![cfg_attr(not(feature = "std"), no_std)]57extern crate alloc;5859use core::ops::{Deref,
