Implementations§

Source§

impl CommandUtil

运行命令工具类 运行命令 例如 linux shell 命令

Source

pub fn exec(program: &str, args: Vec<&str>) -> Result<String, Error>

Execute system command and return output 执行系统命令并返回输出

§Arguments
  • program: Command name (e.g. “ls”)
  • args: Command arguments vector
§Returns
  • Ok(String): Command output
  • Err(Error): Execution failure
Source

pub fn exec_from_str(command: &str) -> Result<String, Error>

Execute command from string format 从字符串格式执行命令

Example:

CommandUtil::exec_from_str("ls -l")
Source

pub fn exec_and_fallback<F>(command: &str, fallback: F) -> Result<String, Error>
where F: FnOnce(),

Execute command with fallback function 带后备函数的命令执行

§Parameters
  • fallback: Function to call when command fails
Source

pub fn exec_to_channel( command: &str, sender: Sender<String>, block: bool, ) -> Result<(), Error>

执行命令并将持续输出通过通道发送。

§参数
  • command: 要执行的命令字符串。
  • sender: 一个 Sender<String>,用于发送命令的输出。
  • block: 是否阻塞当前线程以等待命令完成。
§返回值

如果命令执行成功,则返回 Ok(());否则返回错误
