A pallet governing Unique transactions.20//!21//! - [`Config`]22//! - [`Call`]23//! - [`Pallet`]24//!25//! ## Overview26//!27//! The Unique pallet's purpose is to be the primary interface between28//! external users and the inner structure of the Unique chains.29//!30//! It also contains an implementation of [`CollectionHelpers`][`eth`],31//! an Ethereum contract dealing with collection operations.32//!33//! ## Interface34//!35//! ### Dispatchables36//!37//! - `create_collection` - Create a collection of tokens. **Deprecated**, use `create_collection_ex`.38//! - `create_collection_ex` - Create a collection of tokens with explicit parameters.39//! - `destroy_collection` - Destroy a collection if no tokens exist within.40//! - `add_to_allow_list` - Add an address to allow list.41//! - `remove_from_allow_list` - Remove an address from allow list.42//! - `change_collection_owner` - Change the owner of the collection.43//! - `add_collection_admin` - Add an admin to a collection.44//! - `remove_collection_admin` - Remove admin of a collection.45//! - `set_collection_sponsor` - Invite a new collection sponsor.46//! - `confirm_sponsorship` - Confirm own sponsorship of a collection, becoming the sponsor.47//! - `remove_collection_sponsor` - Remove a sponsor from a collection.48//! - `create_item` - Create an item within a collection.49//! - `create_multiple_items` - Create multiple items within a collection.50//! - `set_collection_properties` - Add or change collection properties.51//! - `delete_collection_properties` - Delete specified collection properties.52//! - `set_token_properties` - Add or change token properties.53//! - `delete_token_properties` - Delete token properties.54//! - `set_token_property_permissions` - Add or change token property permissions of a collection.55//! - `create_multiple_items_ex` - Create multiple items within a collection with explicitly specified initial parameters.56//! - `set_transfers_enabled_flag` - Completely allow or disallow transfers for a particular collection.57//! - `burn_item` - Destroy an item.58//! - `burn_from` - Destroy an item on behalf of the owner as a non-owner account.59//! - `transfer` - Change ownership of the token.60//! - `transfer_from` - Change ownership of the token on behalf of the owner as a non-owner account.61//! - `approve` - Allow a non-permissioned address to transfer or burn an item.62//! - `set_collection_limits` - Set specific limits of a collection.63//! - `set_collection_permissions` - Set specific permissions of a collection.64//! - `repartition` - Re-partition a refungible token, while owning all of its parts.6566#![recursion_limit = "1024"]67#![cfg_attr(not(feature = "std"),
