pub struct Output {

    pub stdout: Vec<u8>,
    pub stderr: Vec<u8>,
}

Expand description

The status (exit code) of the process.

The data that the process wrote to stdout.

The data that the process wrote to stderr.

🔬This is a nightly-only experimental API. (exit_status_error #84908)

Returns an error if a nonzero exit status was received.

If the Command exited successfully,self is returned.

This is equivalent to calling exit_okon Output.status.

Note that this will throw away the Output::stderr field in the error case. If the child process outputs useful informantion to stderr, you can:

Use cmd.stderr(Stdio::inherit()) to forward the stderr child process to the parent’s stderr, usually printing it to console where the user can see it. This is usually correct for command-line applications.
Capture stderr using a custom error type. This is usually correct for libraries.

#![feature(exit_status_error)]
use std::process::Command;
assert!(Command::new("false").output().unwrap().exit_ok().is_err());

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
