Pallas Addresses

安装

在项目目录中运行以下Cargo命令：

cargo add pallas-addresses

或者在Cargo.toml中添加以下行：

pallas-addresses = "0.33.0"

使用示例

以下是一个完整的示例，展示如何使用pallas-addresses库生成和解析Cardano加密货币地址：

use pallas_addresses::{Address, Network};

fn main() {
    // 生成一个新的Cardano地址
    let network = Network::Testnet;
    let address = Address::generate(network);
    
    println!("Generated Address: {}", address.to_bech32().unwrap());
    
    // 解析地址
    let parsed_address = Address::from_bech32("addr_test1qzx9hu8j4ah3fytzq63rkxdpjc65jchn5s33tnh3222q68f0vqd6aflnc0rr5thx4rs0f85z0a0g4k9q8u0yqergd0qq5hl0p3").unwrap();
    
    println!("Parsed Address Details:");
    println!("Network: {:?}", parsed_address.network());
    println!("Payment Credential: {:?}", parsed_address.payment_credential());
    println!("Stake Credential: {:?}", parsed_address.stake_credential());
}

功能说明

pallas-addresses库提供以下主要功能：

支持Cardano等加密货币地址的生成
地址解析功能
支持多种网络类型（主网、测试网等）
Bech32格式地址编码/解码

完整示例代码

以下是一个扩展的使用示例，展示更多pallas-addresses库的功能：

use pallas_addresses::{Address, Network, Error};

fn main() -> Result<(), Error> {
    // 1. 生成不同网络类型的地址
    let testnet_address = Address::generate(Network::Testnet);
    let mainnet_address = Address::generate(Network::Mainnet);
    
    println!("Testnet Address: {}", testnet_address.to_bech32()?);
    println!("Mainnet Address: {}", mainnet_address.to_bech32()?);
    
    // 2. 验证地址有效性
    let valid_address = "addr_test1qzx9hu8j4ah3fytzq63rkxdpjc65jchn5s33tnh3222q68f0vqd6aflnc0rr5thx4rs0f85z0a0g4k9q8u0yqergd0qq5hl0p3";
    match Address::from_bech32(valid_address) {
        Ok(addr) => println!("Address is valid, network: {:?}", addr.network()),
        Err(e) => println!("Invalid address: {}", e),
    }
    
    // 3. 获取地址的原始字节
    let bytes = testnet_address.to_bytes();
    println!("Address bytes: {:?}", bytes);
    
    // 4. 从字节重建地址
    let rebuilt = Address::from_bytes(&bytes, Network::Testnet)?;
    println!("Rebuilt Address: {}", rebuilt.to_bech32()?);
    
    Ok(())
}

功能说明详解

地址生成：支持生成Cardano主网和测试网地址
地址验证：可以验证地址字符串的合法性
格式转换：支持在Bech32格式和原始字节之间转换
网络识别：自动识别地址所属的网络类型

注意事项

使用前请确保添加了正确版本的依赖
生成测试网地址时使用Network::Testnet
所有方法都可能返回错误，建议使用Result处理
Bech32编解码可能失败，需要处理unwrap或使用?

错误处理

建议使用Rust的错误处理机制来处理可能出现的错误：

match Address::from_bech32("invalid_address") {
    Ok(addr) => {
        // 处理有效地址
    },
    Err(e) => {
        // 处理错误情况
        eprintln!("Error: {}", e);
    }
}

Rust区块链地址处理库pallas-addresses使用指南

以下是一个完整的示例demo，展示了如何使用pallas-addresses库进行Cardano地址的生成、解析和验证：

// 主文件：src/main.rs
use pallas_addresses::{Address, Network, AddressType};
mod address_utils;

fn main() {
    // 示例公钥哈希 (实际应用中应从安全来源获取)
    let pubkey_hash = vec![0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef];
    
    // 1. 生成主网地址
    let mainnet_address = address_utils::generate_payment_address(pubkey_hash.clone(), Network::Mainnet);
    println!("生成的主网地址: {}", mainnet_address);
    
    // 2. 生成测试网地址
    let testnet_address = address_utils::generate_payment_address(pubkey_hash, Network::Testnet);
    println!("生成的测试网地址: {}", testnet_address);
    
    // 3. 解析地址示例
    let example_address = "addr1qx2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzer3n0d3vllmyqwsx5wktcd8cc3sq835lu7drv2xwl2wywfgse35a3x";
    match Address::from_base58(example_address) {
        Ok(address) => {
            println!("\n解析地址详情:");
            println!("网络类型: {:?}", address.network());
            println!("地址类型: {:?}", address.address_type());
            println!("地址内容: {:?}", address.payload());
        }
        Err(e) => println!("解析错误: {}", e),
    }
    
    // 4. 地址验证示例
    println!("\n地址验证结果:");
    if address_utils::is_valid_address(example_address) {
        println!("地址 {} 有效", example_address);
    } else {
        println!("地址 {} 无效", example_address);
    }
    
    // 5. 处理不同类型地址
    println!("\n地址类型识别:");
    process_address_types(example_address);
}

fn process_address_types(addr_str: &str) {
    if let Ok(address) = Address::from_base58(addr_str) {
        match address.address_type() {
            AddressType::Base => println!("这是一个基础支付地址"),
            AddressType::Enterprise => println!("这是一个企业地址"),
            AddressType::Stake => println!("这是一个权益地址"),
            _ => println!("其他类型地址"),
        }
    }
}

// 工具模块：src/address_utils.rs
use pallas_addresses::{Address, Network};

/// 生成支付地址
pub fn generate_payment_address(pubkey_hash: Vec<u8>, network: Network) -> String {
    let address = Address::new(network, pubkey_hash);
    address.to_base58()
}

/// 验证地址有效性
pub fn is_valid_address(addr_str: &str) -> bool {
    Address::from_base58(addr_str).is_ok()
}

// 测试文件：src/tests/address_tests.rs
use pallas_addresses::{Address, Network};
use super::address_utils;

#[test]
fn test_address_generation() {
    let test_hash = vec![0x01, 0x02, 0x03, 0x04];
    let address = address_utils::generate_payment_address(test_hash.clone(), Network::Testnet);
    
    assert!(address_utils::is_valid_address(&address));
    assert!(address.starts_with("addr_test"));
}

#[test]
fn test_mainnet_address() {
    let test_hash = vec![0x01, 0x02, 0x03, 0x04];
    let address = address_utils::generate_payment_address(test_hash, Network::Mainnet);
    
    assert!(address_utils::is_valid_address(&address));
    assert!(address.starts_with("addr1"));
}
