Enum WaitStatus

pub enum WaitStatus {
    Exited(pid_t, c_int),
    Signaled(pid_t, Signal, bool),
    Stopped(pid_t, Signal),
    Continued(pid_t),
}

A WaitStatus is the result of wait()ing for a child process

Variants

Exited(pid_t, c_int)

Process exited normally with the given return code

Signaled(pid_t, Signal, bool)

Process was signaled by Signal. If a core dump was produced, the third field is true.

Stopped(pid_t, Signal)

Process is still alive, but was stopped by Signal

Continued(pid_t)

Process was stopped but has resumed execution after receiving a SIGCONT signal

Implementations

impl WaitStatus

pub fn from_raw(pid: pid_t, status: c_int) -> Result<WaitStatus>

Convert a raw status as returned by libc::waitpid() into a WaitStatus

This function is using the standard set of wait status related macros in order to dissect status

Trait Implementations

impl Clone for WaitStatus

fn clone(&self) -> WaitStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WaitStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WaitStatus

fn eq(&self, other: &WaitStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
