[−][src]Trait process_control::ChildExt

pub trait ChildExt: Sealed {
    fn terminator(&self) -> IoResult<Terminator>;

#[must_use]
    fn with_timeout(&mut self, time_limit: Duration) -> _ExitStatusTimeout;

#[must_use]
    fn with_output_timeout(self, time_limit: Duration) -> _OutputTimeout;
}

Extensions to Child for easily terminating processes.

For more information, see the module-level documentation.

Required methods

fn terminator(&self) -> IoResult<Terminator>

Creates an instance of Terminator for this process.

Examples

use std::process::Command;

use process_control::ChildExt;

let process = Command::new("echo").spawn()?;
let terminator = process.terminator()?;

#[must_use] fn with_timeout(&mut self, time_limit: Duration) -> _ExitStatusTimeout

Creates an instance of _ExitStatusTimeout for this process.

This method parallels Child::wait when the process must finish within a time limit.

Examples

use std::process::Command;
use std::time::Duration;

use process_control::ChildExt;

let exit_status = Command::new("echo")
    .spawn()?
    .with_timeout(Duration::from_secs(1))
    .terminating()
    .wait()?
    .expect("process timed out");
assert!(exit_status.success());

#[must_use] fn with_output_timeout(self, time_limit: Duration) -> _OutputTimeout

Creates an instance of _OutputTimeout for this process.

This method parallels Child::wait_with_output when the process must finish within a time limit.

Examples

use std::process::Command;
use std::time::Duration;

use process_control::ChildExt;

let output = Command::new("echo")
    .spawn()?
    .with_output_timeout(Duration::from_secs(1))
    .terminating()
    .wait()?
    .expect("process timed out");
assert!(output.status.success());
