The Structure pallet provides functionality for handling tokens nesting an unnesting.20//!21//! - [`Config`]22//! - [`Pallet`]23//!24//! ## Overview25//!26//! The Structure pallet provides functions for:27//!28//! - Searching for token parents, children and owners. Actual implementation of searching for29//!   parent/child is done by pallets corresponding to token's collection type.30//! - Nesting and unnesting tokens. Actual implementation of nesting is done by pallets corresponding31//!   to token's collection type.32//!33//! ### Terminology34//!35//! - **Nesting:** Setting up parent-child relationship between tokens. Nested tokens are inhereting36//!   owner from their parent. There could be multiple levels of nesting. Token couldn't be nested in37//!   it's child token i.e. parent-child relationship graph shouldn't have38//!39//! - **Parent:** Token that current token is nested in.40//!41//! - **Owner:** Account that owns the token and all nested tokens.42//!43//! ## Interface44//!45//! ### Available Functions46//!47//! - `find_parent` - Find parent of the token. It could be an account or another token.48//! - `parent_chain` - Find chain of parents of the token.49//! - `find_topmost_owner` - Find account or token in the end of the chain of parents.50//! - `check_nesting` - Check if the token could be nested in the other token51//! - `nest_if_sent_to_token` - Nest the token in the other token52//! - `unnest_if_nested` - Unnest the token from the other token5354#![cfg_attr(not(feature = "std"), no_std)]5556use pallet_common::CommonCollectionOperations;57use pallet_common::{erc::CrossAccountId, eth::is_collection};58use sp_std::collections::btree_set::BTreeSet;5960use frame_support::dispatch::{DispatchError, DispatchResult, DispatchResultWithPostInfo};61use frame_support::fail;62pub use pallet::*;63use pallet_common::{dispatch::CollectionDispatch};64use up_data_structs::{65	CollectionId, TokenId, mapping::TokenAddressMapping, budget::Budget, TokenOwnerError,66};6768#[cfg(feature = "runtime-benchmarks")]69pub mod benchmarking;70pub mod weights;7172pub type SelfWeightOf<T> = <T as crate::Config>::WeightInfo;7374#[frame_support::pallet]75pub mod pallet {76	use frame_support::Parameter;77	use frame_support::dispatch::{GetDispatchInfo, UnfilteredDispatchable};78	use frame_support::pallet_prelude::*;7980	use super::*;8182	#[pallet::error]83	pub enum Error<T> {84		/// While nesting, encountered an already checked account, detecting a loop.85		OuroborosDetected,86		/// While nesting, reached the depth limit of nesting, exceeding the provided budget.87		DepthLimit,88		/// While nesting, reached the breadth limit of nesting, exceeding the provided budget.89		BreadthLimit,90		/// Couldn't find the token owner that is itself a token.91		TokenNotFound,92		/// Tried to nest token under collection contract address, instead of token address93		CantNestTokenUnderCollection,94	}9596	#[pallet::event]97	pub enum Event<T> {98		/// Executed call on behalf of the token.99		Executed(DispatchResult),100	}101102	#[pallet::config]103	pub trait Config: frame_system::Config + pallet_common::Config {104		type WeightInfo: weights::WeightInfo;105		type RuntimeEvent: IsType<<Self as frame_system::Config>::RuntimeEvent> + From<Event<Self>>;106		type RuntimeCall: Parameter107			+ UnfilteredDispatchable<RuntimeOrigin = Self::RuntimeOrigin>108			+ GetDispatchInfo;109	}110111	#[pallet::pallet]112	pub struct Pallet<T>(_);113114	#[pallet::call]115	impl<T: Config> Pallet<T> {116		// #[pallet::weight({117		// 	let dispatch_info = call.get_dispatch_info();118119		// 	(120		// 		dispatch_info.weight121		// 			// Cost of dereferencing parent122		// 			.saturating_add(T::DbWeight::get().reads(2 * *max_depth as Weight))123		// 			.saturating_add(4000 * *max_depth as Weight),124		// 		dispatch_info.class)125		// })]126		// pub fn execute(127		// 	origin: OriginFor<T>,128		// 	call: Box<<T as Config>::Call>,129		// 	max_depth: u32,130		// ) -> DispatchResult {131	}132}133134#[derive(PartialEq)]135pub enum Parent<CrossAccountId> {136	/// Token owned by a normal account.137	User(CrossAccountId),138	/// Could not find the token provided as the owner.139	TokenNotFound,140	/// Nested token has multiple owners.141	MultipleOwners,142	/// Token owner is another token (still, the target token may not exist).143	Token(CollectionId, TokenId),144}145146impl<T: Config> Pallet<T> {147	/// Find account owning the `token` or a token that the `token` is nested in.148	///149	/// Returns the enum that have three variants:150	/// -
