1.1 move Generics
创建合约项目
sui move new generics && cd generics新建generics.move
module generics::generics {
use sui::transfer;
use sui::object::{Self, UID};
use sui::tx_context::{Self, TxContext};
struct Box<T: store> has key, store {
id: UID,
value: T
}
struct SimpleBox has key, store {
id: UID,
value: u8
}
struct PhantomBox<phantom T: drop> has key {
id: UID,
}
public fun create_box<T: store>(value: T, ctx: &mut TxContext){
transfer::transfer(Box<T> {id: object::new(ctx), value }, tx_context::sender(ctx))
}
public fun create_simple_box(value: u8, ctx: &mut TxContext){
transfer::transfer(SimpleBox {id: object::new(ctx), value }, tx_context::sender(ctx))
}
public fun create_phantom_box<T: drop >(_value: T, ctx: &mut TxContext){
transfer::transfer(PhantomBox<T> {id: object::new(ctx)}, tx_context::sender(ctx))
}
}部署合约
sui client publish --gas-budget 100000000 --skip-dependency-verification

│ │ Modules: generics 调用create_box创建box
将之前创建的helloworld存储到box
sui client call --package 0xab619c63c6ad6d3e5cc94875913f85b6957bc77d8706b54a95f4f6fd5d72bd13 --module generics --function create_box --args 0x0496c2f2fccf89ebab659324f4735297a06d0c45a54348babf1443ced89ea796 --type-args "0x2ddc2bd1445a8046487b645cb4626764ea812f62bdaef8253182719a96c81426::hello_world::HelloWorldObject" --gas-budget 1000000
将sui代币存储到box
sui client call --package 0xab619c63c6ad6d3e5cc94875913f85b6957bc77d8706b54a95f4f6fd5d72bd13 --module generics --function create_box --args 0xb4fbb54b7ee3d76b6d04787f48b44113efc4228e7803aa3b0b8bea410b9c43b3 --type-args "0x2::coin::Coin<0x2::sui::SUI>" --gas-budget 10000000
但是如果放入的类型本身不拥有 store 能力，则无法被存储
sui client call --package 0xab619c63c6ad6d3e5cc94875913f85b6957bc77d8706b54a95f4f6fd5d72bd13 --module generics --function create_box --args 0x6b2a315363bb27da5628a2271b161c78eeb364826f68c0b84cc34e750cbcb0e5 --type-args "0x86cac9f3c094c7e0bfed3aae880a4400130626d4aacc2ada137554b6b7ae50c3::transcript::Folder" --gas-budget 10000000
查看之前的代码，Folder只拥有key的能力
struct Folder has key {
id: UID,
transcript: WrappableTranscript,
intended_address: address
}1.2 Generics解封装
解封装拿出sui，新增transfer_value函数
public fun transfer_value<T: key + store>(box: Box<T>, ctx: &mut TxContext) {
let Box{
id,
value
}= box;
transfer::public_transfer<T>(value, tx_context::sender(ctx));
object::delete(id)
}然后需要进行合约upgrade，需要先获取第一次发布合约时获取的UpgradeCap
0xa4238a21ba7c9832d4e3b3b4a5a814fbb234a60309b5cc2259b501a81f6235a4然后修改move.toml文件，新增publish-at参数填入已发布合约的packageid
[package]
name = "generics"
version = "0.0.1"
published-at = "0xab619c63c6ad6d3e5cc94875913f85b6957bc77d8706b54a95f4f6fd5d72bd13"
[dependencies]
Sui = { git = "https://github.com/MystenLabs/sui.git", subdir = "crates/sui-framework/packages/sui-framework", rev = "framework/mainnet" }
[addresses]
generics = "0x0"然后执行upgrade命令，这里面填入的就是UpgradeCap objectid
sui client upgrade --upgrade-capability 0x560bf0c92d904b64dc6988c6267b7c869b31e411684e8657ae065b3707d643ad --gas-budget 100000000 --skip-dependency-verification然后更新合约之后执行解封装
sui client call --package 0x3a00c46eb80db77c807af34b37e8a10c8df5285d6d66b8741a755c73886c566e --module generics --function transfer_value --args 0xfe8f1d8d3ef7b2da414084a331c8f50ab138cd2483dcd2f82500cb1c382a0b39 --type-args "0x2::coin::Coin<0x2::sui::SUI>" --gas-budget 10000000然后查看钱包地址，sui已经转移回来了
1.3 Witness设计模式
witness合约创建
sui move new witness && cd witnes新建witness.move
module witness::peace {
use sui::object::{Self, UID};
use sui::transfer;
use sui::tx_context::{Self, TxContext};
/// Phantom parameter T can only be initialized in the `create_guardian`
/// function. But the types passed here must have `drop`.
struct Guardian<phantom T: drop> has key, store {
id: UID
}
/// This type is the witness resource and is intended to be used only once.
struct PEACE has drop {}
/// The first argument of this function is an actual instance of the
/// type T with `drop` ability. It is dropped as soon as received.
public fun create_guardian<T: drop>(
_witness: T, ctx: &mut TxContext
): Guardian<T> {
Guardian { id: object::new(ctx) }
}
/// Module initializer is the best way to ensure that the
/// code is called only once. With `Witness` pattern it is
/// often the best practice.
fun init(witness: PEACE, ctx: &mut TxContext) {
transfer::transfer(
create_guardian(witness, ctx),
tx_context::sender(ctx)
)
}
}合约部署后init调用create_guardian创建一个Guardian<T>资源实例，即Guardian<PEACE>，_witness 参数：这是一个类型为 T 的参数，传入函数时立即被放弃，这符合传入类型必须具备的 drop 能力。

│ └── │然后查询也可以看到根据代码存储了新建的objectid
struct Guardian<phantom T: drop> has key, store {
id: UID
}
在该模式中，可以确保某些行为（比如合约的初始化过程）只被执行一次。
1.4 发布STOMCOIN
新建stomcoin项目，然后新建stomcoin.move
module stomcoin::stomcoin{
use std::option;
use sui::coin::{Self, Coin, TreasuryCap};
use sui::transfer;
use sui::tx_context::{Self, TxContext};
//coin's name
struct STOMCOIN has drop {}
//init
fun init(witness: STOMCOIN,ctx: &mut TxContext) {
let (treasury_cap,metadata) = coin::create_currency<STOMCOIN>(witness, 2, b"STOMCOIN", b"SC", b"", option::none(), ctx);
transfer::public_freeze_object(metadata);
transfer::public_transfer(treasury_cap, tx_context::sender(ctx))
}
//mint new coins
public fun mint(
treasury_cap: &mut TreasuryCap<STOMCOIN>, amount: u64, recipient: address, ctx: &mut TxContext
) {
coin::mint_and_transfer(treasury_cap, amount, recipient, ctx)
}
//burn coins
public fun burn(treasury_cap: &mut TreasuryCap<STOMCOIN>, coin: Coin<STOMCOIN>) {
coin::burn(treasury_cap, coin);
}
#[test_only]
// Wrapper of module initializer for testing
public fun test_init(ctx: &mut TxContext) {
init(STOMCOIN {}, ctx)
}
}部署合约后获取TreacuryCap和packageid

1.5 发布STOMLOCKCOIN
module stomlockcoin::stomlockcoin{
