Struct std::process::ExitStatus 1.0.0
[−]
[src]
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]
fn success(&self) -> bool
Was termination successful? Signal termination 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
fn code(&self) -> Option<i32>
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
