Rust区块链工具库solana-cli-output的使用指南
概述
solana-cli-output是一个专为Solana区块链开发者设计的Rust工具库，用于解析和格式化Solana命令行工具的输出结果。该库提供了简洁的API来处理Solana CLI的各种输出格式，使开发者能够更轻松地集成和处理区块链数据。
主要功能
- 解析Solana CLI的JSON输出
- 格式化交易和账户信息
- 处理错误信息和状态码
- 支持自定义输出模板
安装方法
在Cargo.toml中添加依赖：
[dependencies]
solana-cli-output = "0.1.0"
基本用法
1. 解析账户信息
use solana_cli_output::{parse_account_output, DisplayFormat};
fn main() {
let json_output = r#"
{
"pubkey": "9wFFyR8...",
"lamports": 1461600,
"owner": "11111111111111111111111111111111",
"executable": false
}"#;
match parse_account_output(json_output) {
Ok(account_info) => {
println!("账户余额: {} SOL", account_info.lamports_to_sol());
println!("格式化输出:\n{}", account_info.format(DisplayFormat::Human));
}
Err(e) => eprintln!("解析错误: {}", e),
}
}
2. 处理交易结果
use solana_cli_output::{parse_transaction_output, TransactionDisplay};
fn handle_transaction() {
let tx_output = r#"
{
"slot": 12345,
"transaction": {
"signatures": ["5Q..."],
"message": {"instructions": [...]}
},
"meta": {
"err": null,
"fee": 5000,
"status": {"Ok": null}
}
}"#;
let tx_info = parse_transaction_output(tx_output).unwrap();
println!("交易状态: {}", tx_info.status());
println!("手续费: {} lamports", tx_info.fee());
}
3. 自定义格式化
use solana_cli_output::{OutputParser, CustomFormatter};
fn custom_formatting() {
let parser = OutputParser::new();
let formatter = CustomFormatter::new()
.with_date_format("%Y-%m-%d %H:%M:%S")
.with_number_separators(true);
let data = get_solana_cli_data(); // 获取CLI输出
let formatted = parser.parse_and_format(data, &formatter);
println!("{}", formatted);
}
高级特性
错误处理
use solana_cli_output::{ErrorParser, CliError};
fn analyze_errors() {
let error_output = r#"
{
"code": 123,
"message": "Insufficient funds",
"data": {"required": 1000000, "available": 500000}
}"#;
match ErrorParser::parse(error_output) {
Ok(cli_error) => {
println!("错误代码: {}", cli_error.code);
println!("建议解决方案: {}", cli_error.suggest_solution());
}
Err(e) => eprintln!("无法解析错误信息: {}", e),
}
}
批量处理
use solana_cli_output::BatchProcessor;
async fn process_multiple_outputs() {
let outputs = vec![output1, output2, output3];
let processor = BatchProcessor::new()
.with_concurrency(4)
.with_timeout(std::time::Duration::from_secs(30));
let results = processor.process_batch(outputs).await;
for result in results {
println!("处理结果: {:?}", result);
}
}
配置选项
use solana_cli_output::{OutputConfig, NumberFormat, DateStyle};
let config = OutputConfig::default()
.number_format(NumberFormat::Commas)
.date_style(DateStyle::Relative)
.max_decimals(6)
.show_all_fields(false);
