一：Logistics Company 功能介绍
- 所有人都可以创建独属于自己的物流公司，按照每百克的价格定价（不满100g的将按照100g计算），当然，公司所有者也可以注销这所公司，但前提是处理完所有的业务。
- 所有人都可以是顾客，提供将要运输的物品信息（主要是重量）进行下单，同时支付费用。
- 类似于现今的各大消费平台，支付的费用不会直接抵达公司的账户下，而是存储在平台的某个地方（在这里，就是 <math xmlns="http://www.w3.org/1998/Math/MathML"> S u i \mathit {Sui} </math>Sui 链上的某个对象中，不提供对该对象内的金额直接提现的功能），只有用户凭借快递单确认收货，或者超过15个周期由公司进行确认收货操作后，对应的款项才会打入公司的账户。
- 只有进入公司账户的收益额，管理者才能够将其提现到自己的钱包，当然，为了该平台的可持续发展，每一笔提现，需要支付给平台创始人 <math xmlns="http://www.w3.org/1998/Math/MathML"> 1 % \text 1\% </math>1% 的抽成。
- 平台创始人可以通过对抽成得到的收益进行提现。
- 下单后不超过3个周期，顾客可以凭快递单进行退款操作，金额将原封不动退入消费者账户钱包。
二：结构定义
2.1 平台创始人
需要一个Balance<SUI>来存储提成，所以该对象需要共享可变。
但是提现操作只能是创始人自己，因此通过 <math xmlns="http://www.w3.org/1998/Math/MathML"> O n e \mathit {One} </math>One- <math xmlns="http://www.w3.org/1998/Math/MathML"> T i m e \mathit {Time} </math>Time- <math xmlns="http://www.w3.org/1998/Math/MathML"> W i t n e s s \mathit {Witness} </math>Witness 来创建一个Publisher在后续调用时表明身份。
move
// Define ADMIN(one time witness) struct
struct ADMIN has drop {}
// Define Admin struct
struct Admin has key {
id: UID,
balance: Balance<SUI>,
}2.2 公司
公司的各项信息都应该透明，尤其是价格方面，所以该对象也应该是共享甚至是可变的，因为当顾客下单后，需要将物品相关信息暂存入公司。
类似的，收益提现以及由公司确认收货操作都需要公司管理者才有权限，因此再创建一个所有者为个人的凭证对象。
move
// Define CompanyCap struct
struct CompanyCap has key {
id: UID,
}
// Define Company struct
struct Company has key {
id: UID,
name: String,
price_per_hundred_grams: u64,
waiting_for_receipt: LinkedTable<ID, ItemInfo>,
can_be_cashed: Balance<SUI>,
all_profit: u64,
}其中用到了LinkedTable，这是一个通过 <math xmlns="http://www.w3.org/1998/Math/MathML"> K e y \mathit {Key} </math>Key- <math xmlns="http://www.w3.org/1998/Math/MathML"> V a l u e \mathit {Value} </math>Value 存储的自带的数据结构，拥有头插，尾插，从头部取出，从尾部取出等功能，用来维护待确认收货的物流信息比较合适，具体可以点击查看源码。
2.3 物流
顾客下单后会得到与公司相对应的快递单（通过公司的 <math xmlns="http://www.w3.org/1998/Math/MathML"> I D \mathit {ID} </math>ID 进行对应），该快递单不对外公开，仅下单的顾客拥有。
同时生成相对应的信息，包括下单时期以及金额等。
move
// Define TransportItem struct
struct TransportItem has key {
id: UID,
logistics_company: String,
company_id: ID,
weight: u64,
price: u64,
}
// Define ItemInfo struct
struct ItemInfo has store {
epoch: u64,
transport_price: Balance<SUI>,
}三：功能实现
3.1 平台创始人
3.1.1 发布时初始化
在发布该合约的时候自动调用的init函数当中，通过只能在这里使用的 <math xmlns="http://www.w3.org/1998/Math/MathML"> O n e \mathit {One} </math>One- <math xmlns="http://www.w3.org/1998/Math/MathML"> T i m e \mathit {Time} </math>Time- <math xmlns="http://www.w3.org/1998/Math/MathML"> W i t n e s s \mathit {Witness} </math>Witness 来创建Publisher，并将其拥有权递交给发布者。
同时，在该函数当中，创建一个共享可变的Admin，用作各大公司提现时获取提成的账户。
move
// Function to init the publisher and admin
fun init(otw: ADMIN, ctx: &mut TxContext) {
// create Publisher and transfer it to the sender
package::claim_and_keep(otw, ctx);
// create Admin and share it with all users
transfer::share_object(Admin {
id: object::new(ctx),
balance: balance::zero(),
});
}3.1.2 提现
通过Publisher确认身份，当Admin当中的抽成大于零的时候可以对其进行提现（将 <math xmlns="http://www.w3.org/1998/Math/MathML"> S U I \mathit {SUI} </math>SUI 的 <math xmlns="http://www.w3.org/1998/Math/MathML"> b a l a n c e \mathit {balance} </math>balance 包装成 <math xmlns="http://www.w3.org/1998/Math/MathML"> C o i n \mathit {Coin} </math>Coin 发送给平台创始人）。
move
// Function to withdraw(only the publisher can withdraw)
public entry fun withdraw(_publisher: &Publisher, admin: &mut Admin, ctx: &mut TxContext) {
// get the value amount
let amount = balance::value(&admin.balance);
// it's necessary to make sure the amount > 0
assert!(amount > 0, ERROR_NOT_BALANCE);
// transfer the coin with the all balance to the sender
transfer::public_transfer(coin::take(&mut admin.balance, amount, ctx), tx_context::sender(ctx));
}3.2 公司
3.2.1 创建公司
不仅要根据信息创建公开的Company，还需要创建仅创建者持有的CompanyCap用作后续的身份凭证（在这里的功能效果类似于上面的Publisher）。
move
// Function to create company
public entry fun create_company(name: String, price_per_hundred_grams: u64, ctx: &mut TxContext) {
// create CompanyCap and transfer it to the sender
// this is a testament to the company's managers
transfer::transfer(CompanyCap {
id: object::new(ctx),
}, tx_context::sender(ctx));
// create Company and share it with all users
transfer::share_object(Company {
id: object::new(ctx),
name,
price_per_hundred_grams,
waiting_for_receipt: linked_table::new<ID, ItemInfo>(ctx),
can_be_cashed: balance::zero(),
all_profit: 0,
});
}3.2.2 确认收货
只有下单后超过 <math xmlns="http://www.w3.org/1998/Math/MathML"> 15 \text {15} </math>15 个周期的货物，公司有权进行确认收货操作。
在此之前，我们先来明确一个隐性的条件，那就是每当有顾客下单，对应的信息被push_back进linked_table，其中所存储的epoch是下单时的值，而下单这个操作本身是有序的，时间也不可能乱序，所以在link_table中所存储的信息，从前到后的epoch理论上来说也应该是非严格递增的。
基于上述理论，在该函数当中，可以通过从前到后的循环进行，直到linked_table为空或者front不满足epoch条件时跳出循环。
为了更清晰明了地演示一步步地取值过程，这里采用了loop无限循环（要注意其跳出循环的条件，因为合约发布时并不能明确这是否是正确的），如果对取值以及数据之间调用比较熟悉的，可以直接将跳出循环的条件写在一起当做判决用while。
当然，想要进行这一操作，需要你拥有对应公司的管理员权限，也就是CompanyCap。
move
// Function to unconfirmed receipt items with confirmation epoch greater than 15
// Company managers can only confirm the company's transport items
public entry fun confirm_items(_company_cap: &CompanyCap, company: &mut Company, ctx: &mut TxContext) {
// get the now epoch
let now_epoch = tx_context::epoch(ctx);
// to be confirmed list
let items = &mut company.waiting_for_receipt;
// theoretically, the linked table is sorted according to epoch
// because when user call function, linked_table push_back, this is orderly in itself
loop {
// items need to be not empty
if (linked_table::is_empty(items)) break;
// linked_table::front -> &Option<Element>
// option::borrow -> &Element
// in this module, Element is ID
let key = *option::borrow(linked_table::front(items));
// linked_table::borrow -> &Value
// in this module, Value is ItemInfo
let transport_epoch = linked_table::borrow(items, key).epoch;
// the front item's epoch is longer than 15
if (transport_epoch + 15 >= now_epoch) break;
// pop the front and get the ItemInfo
let (_, item_info) = linked_table::pop_front(items);
// destroy ItemInfo and get the price
let ItemInfo {
epoch: _,
transport_price,
} = item_info;
// add to the all_profit
company.all_profit = company.all_profit + balance::value(&transport_price);
// add the profit
balance::join(&mut company.can_be_cashed, transport_price);
};
}3.2.3 提现
需要管理员权限CompanyCap才可调用，这里的关键是需要取出 <math xmlns="http://www.w3.org/1998/Math/MathML"> 1 % \text 1\% </math>1% 存入Admin，由于 <math xmlns="http://www.w3.org/1998/Math/MathML"> M o v e \mathit {Move} </math>Move 语言目前对浮点数的支持有限，所以这里平台创始人吃点亏，只抽取 <math xmlns="http://www.w3.org/1998/Math/MathML"> ⌊ p r o f i t 100 ⌋ \lfloor \frac{\mathit{profit}}{\text{100}} \rfloor </math>⌊100profit⌋。
move
// Function to cash
public entry fun cash(_company_cap: &CompanyCap, admin: &mut Admin, company: &mut Company, ctx: &mut TxContext) {
// get the amount of balance
let can_be_cashed = &mut company.can_be_cashed;
let amount = balance::value(can_be_cashed);
// check the amount
assert!(amount > 0, ERROR_NOT_BALANCE);
// admin profit: 1% of the balance
let admin_profit = balance::split(can_be_cashed, amount / 100);
// add to the admin balance
let admin_balance = admin::get_balance_mut(admin);
balance::join(admin_balance, admin_profit);
// the remaining amount belongs to the company
amount = balance::value(can_be_cashed);
transfer::public_transfer(coin::take(can_be_cashed, amount, ctx), tx_context::sender(ctx));
}3.2.4 注销公司
解构创建的与公司有关的对象，也就是CompanyCap和Company，注意，后者内部的LinkedTable和Balance都需要手动摧毁，如果其中不为空，则会报错，同时恢复到该交易之前的状态。
move
// Function to destroy company
public entry fun destroy_company(company_cap: CompanyCap, company: Company) {
// deconstruct the CompanyCap
let CompanyCap {id} = company_cap;
// delete the id
object::delete(id);
// deconstruct the Company
let Company {
id,
name: _,
price_per_hundred_grams: _,
waiting_for_receipt,
can_be_cashed,
all_profit: _,
} = company;
// delete the id
object::delete(id);
// destroy linked_table
linked_table::destroy_empty(waiting_for_receipt);
// destroy balance
balance::destroy_zero(can_be_cashed);
}3.3 物流
3.3.1 创建（下单）
选择公司，提供物品重量，支付对应的金额（多退少报错），顾客得到仅自己可见的快递单，而对应的信息则存储入Company当中的LinkedTable，其中作为 <math xmlns="http://www.w3.org/1998/Math/MathML"> K e y \mathit {Key} </math>Key 的 <math xmlns="http://www.w3.org/1998/Math/MathML"> I D \mathit {ID} </math>ID 取自对应的快递单，也就是TransportItem。
move
// Function to create transport item
public entry fun create_item(company: &mut Company, weight: u64, sui: Coin<SUI>, ctx: &mut TxContext) {
// if the weight is less than 100g, it will be calculated as 100g
// in other words: weight / 100 rounded up multiply by price_per_hundred_grams
let price = (weight + 99) / 100 * company.price_per_hundred_grams;
// check enough price
assert!(coin::value(&sui) >= price, ERROR_NOT_ENOUGH_COIN);
// split the right price
let transport_price = coin::split(&mut sui, price, ctx);
// destroy or transfer the remaining coin to the owner
if (coin::value(&sui) == 0) {
coin::destroy_zero(sui);
} else {
transfer::public_transfer(sui, tx_context::sender(ctx));
};
// create TransportItem
let transport_item = TransportItem {
id: object::new(ctx),
logistics_company: company.name,
company_id: object::id(company), // corresponding company ID
weight,
price,
};
// get the ID through transport_item to achieve a one-on-one relationship
let id = object::id(&transport_item);
// create ItemInfo
let item_infomation = ItemInfo {
epoch: tx_context::epoch(ctx),
transport_price: coin::into_balance(transport_price),
};
// transfer the credentials to the user
transfer::transfer(transport_item, tx_context::sender(ctx));
// store the item_info to the company
linked_table::push_back(&mut company.waiting_for_receipt, id, item_infomation);
}3.3.2 退款
下单后不超过 <math xmlns="http://www.w3.org/1998/Math/MathML"> 3 \text 3 </math>3 个周期的订单才可以退款，而且TransportItem当中的company_id必须与退款公司相一致，当然，该订单必须存在且未被确认收货。
move
// Function to refunds if no more than 3 epoch
public entry fun refunds(transport_item: TransportItem, company: &mut Company, ctx: &mut TxContext) {
// check whether it corresponds to the company
assert!(transport_item.company_id == object::id(company), ERROR_NOT_ORDERED_COMPANY);
// get waiting_for_receipt
let waiting_for_receipt = &mut company.waiting_for_receipt;
// get the ID through transport_item
let id_key = object::id(&transport_item);
// determine whether it is the correct item or whether it is receipted
assert!(linked_table::contains(waiting_for_receipt, id_key), ERROR_NOT_ITEM_OR_RECEIPTED);
// must not exceed 3 epochs
assert!(linked_table::borrow(waiting_for_receipt, id_key).epoch + 3 >= tx_context::epoch(ctx), ERROR_NOT_REFUNDS);
// deconstruct the ItemInfo
let ItemInfo {
epoch: _,
transport_price,
} = linked_table::remove(waiting_for_receipt, id_key);
// get the balance amount
let amount = balance::value(&transport_price);
// refunds
transfer::public_transfer(coin::take(&mut transport_price, amount, ctx), tx_context::sender(ctx));
// destroy the zero balance
balance::destroy_zero(transport_price);
// destroy TransportItem
destroy_transport_item(transport_item);
}3.3.3 确认收货
通过TransportItem到对应的Company确认收货，成功后快递单将被销毁，而对应的款项将被转移到公司的账户。
如果该信息已经超过了 <math xmlns="http://www.w3.org/1998/Math/MathML"> 15 \text {15} </math>15 个周期且物流公司确认收货了，那么此函数仅执行销毁快递单的操作。
move
// Function to confirm receipt by correct TransportItem
public entry fun confirm_receipt(transport_item: TransportItem, company: &mut Company) {
// check whether it corresponds to the company
assert!(transport_item.company_id == object::id(company), ERROR_NOT_ORDERED_COMPANY);
// get waiting_for_receipt
let waiting_for_receipt = &mut company.waiting_for_receipt;
// get the ID through transport_item
let id_key = object::id(&transport_item);
// determine whether it is the correct item or whether it is receipted
if (linked_table::contains(waiting_for_receipt, id_key)) {
// deconstruct the ItemInfo
let ItemInfo {
epoch: _,
transport_price,
} = linked_table::remove(waiting_for_receipt, id_key);
// add to the all_profit
company.all_profit = company.all_profit + balance::value(&transport_price);
// add the profit
balance::join(&mut company.can_be_cashed, transport_price);
};
// destroy TransportItem
destroy_transport_item(transport_item);
