Method wait

devx-cmd/src/lib.rs:538–548

Waits for the process to finish. Returns an error if the process has finished with non-zero exit code. You should use this method for processes spawned via [`Cmd::spawn()`] since the output of the command won't be read and returned, but just written to this process's `stdout` (as `stdout` is inherited with [`Cmd::spawn()`])

(&mut self)

    /// but just written to this process's `stdout` (as `stdout` is inherited
    /// with [`Cmd::spawn()`])
    pub fn wait(&mut self) -> Result<()> {
        let exit_status = self.child.wait().proc_context(self)?;

        if !exit_status.success() {
            return Err(Error::proc(
                &self,
                &format_args!("Non-zero exit code: {}", exit_status),
            ));
        }
        Ok(())
    }

    /// Same as [`Child::read()`] but reads any bytes sequence from the
    /// child process `stdout`.
