1.0.0[][src]Struct std::process::ExitStatus

pub struct ExitStatus(_);

Describes the result of a process after it has terminated.

This struct is used to represent the exit status of a child process. Child processes are created via the Command struct and their exit status is exposed through the status method.

Methods

impl ExitStatus
[src]

Was termination successful? Signal termination is not considered a success, and success is defined as a zero exit status.

Examples

use std::process::Command;

let status = Command::new("mkdir")
                     .arg("projects")
                     .status()
                     .expect("failed to execute mkdir");

if status.success() {
    println!("'projects/' directory created");
} else {
    println!("failed to create 'projects/' directory");
}Run

Returns the exit code of the process, if any.

On Unix, this will return None if the process was terminated by a signal; std::os::unix provides an extension trait for extracting the signal and other details from the ExitStatus.

Examples

use std::process::Command;

let status = Command::new("mkdir")
                     .arg("projects")
                     .status()
                     .expect("failed to execute mkdir");

match status.code() {
    Some(code) => println!("Exited with status code: {}", code),
    None       => println!("Process terminated by signal")
}Run
