第一次学 Rust 写了个解压小工具 还挺爽

需求：递归 原地 解压所有压缩文件

以前这种东西都用 python/shell 写

现在正在试着全面转向 rust 的技术栈 反正 rustup 安装也挺方便的（但比 go 还是麻烦了点

(好像设置 rust 和 rs 都没有代码高亮 凑活着看

use std::env; use std::fs; use std::io; use std::path::{Path, PathBuf}; use std::process::Command; fn unar_file(path: &Path) -> io::Result<()> { println!("UNAR: {}", path.display()); let parent_dir = path.parent().unwrap(); let filename = path.file_name().unwrap(); let output = Command::new("unar") .current_dir(parent_dir) .arg("-s") .arg("-d") .arg(filename) .output(); match output { Ok(res) => { if !res.status.success() { eprintln!("Error processing compressed file {:?}: {}", path, String::from_utf8_lossy(&res.stderr)); return Err(io::ErrorKind::Other.into()); } } Err(e) => { eprintln!("Failed to execute unar for {:?}: {}", path, e); } } Ok(()) } fn is_compressed(path: &Path) -> bool { if let Some(ext) = path.extension() { if let Some(ext) = ext.to_str() { let ext = ext.to_lowercase(); return ext == "zip" || ext == "rar" || ext == "7z"; } } false } fn process_compressed_files(path: &Path) -> io::Result<()> { if !path.is_dir() { return Err(io::Error::new(io::ErrorKind::Other, "Not a directory")); } println!("Processing directory: {}", path.display()); for entry in fs::read_dir(path)? { let entry_path = entry?.path(); if entry_path.is_dir() { process_compressed_files(&entry_path)?; } else if is_compressed(entry_path.as_path()) { unar_file(&entry_path).expect("UNAR Error."); } } Ok(()) } fn main() -> io::Result<()> { let args: Vec<String> = env::args().collect(); let start_path = if args.len() > 1 { PathBuf::from(args[1].as_str()) } else { PathBuf::from(".") }; if start_path.is_file() { return unar_file(&start_path); } process_compressed_files(&start_path)?; Ok(()) } 

不知道粗制滥造的代码有没有什么问题 Rust 大佬请指正～
