字符串(Strings)
Move 没有原生的字符串类型但是提供了方便的包装方法。
English Version
Move does not have a native type for strings, but it has a handy wrapper!
module examples::strings {
use sui::object::{Self, UID};
use sui::tx_context::TxContext;
// 使用以下依赖可以使用针对UTF-8的包装函数
// Use this dependency to get a type wrapper for UTF-8 strings
use std::string::{Self, String};
/// 一个包含字符串类型的模拟对象
/// A dummy Object that holds a String type
struct Name has key, store {
id: UID,
/// Here it is - the String type
name: String
}
/// 用输入的字节数据创建一个`Name`对象
/// Create a name Object by passing raw bytes
public fun issue_name_nft(
name_bytes: vector<u8>, ctx: &mut TxContext
): Name {
Name {
id: object::new(ctx),
name: string::utf8(name_bytes)
}
}
}
