Struct std::process::unix::ExitStatus

Describes the result of a process after it has terminated.

Methods

• fn from_wait_status(wait_status: c_int) -> ExitStatus

  source

  Create ExitStatus from an wait status (not exit code).

  Wait status is the return value of functions such as wait and waitpid.

• fn wait_status(self: &ExitStatus) -> i32

  source

  Returns the raw wait status of the process.

  Example

  use std::process::Command;
  use std::fs::Path;
  
  let command = Command::new(Path::new("/usr/bin/false"));
  let status = command.spawn().unwrap().wait().unwrap();
  
  assert_eq!(status.wait_status(), 256); // (1 << 8) | 0
  Run this example

• fn success(self: &ExitStatus) -> bool

  source

  Returns true if process completed successfully

  This implies that the process was not terminated by a signal and that the exit code is 0.

  Example

  use std::process::Command;
  use std::fs::Path;
  
  let command = Command::new(Path::new("/usr/bin/true"));
  let status = command.spawn().unwrap().wait().unwrap();
  
  assert!(status.success());

• fn core_dumped(self: &ExitStatus) -> bool

  source

• fn code(self: &ExitStatus) -> Option<i32>

  source

  Returns exit code of a process, if present.

  If the process was terminated by a signal, this will return Option::none() (see signal).

• fn signal(self: &ExitStatus) -> Option<i32>

  source

  Returns the signal number the process was terminated by.

  If the process was not temrinated by a signal, this will return Option::none() (see code).

• fn equals(self: &ExitStatus, other: &ExitStatus) -> bool

  source

  Returns true if arguments are equal, false otherwise

  See Equatable for details.

• fn hash<H>(self: &ExitStatus, h: &mut H)

  H: Hasher<H>

  source

  Update hasher state with the contents of this object.

  See Hashable for details.

Mixins

• mixin Equatable<ExitStatus>

• fn not_equals(lhs: &Self, rhs: &Self) -> bool

  source

  Returns false if arguments are equal, true otherwise
