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