Struct ExitStatus 

pub struct ExitStatus(/* private fields */);

Describes the result of a process after it has terminated.

Implementations

impl ExitStatus

pub fn exit_ok(&self) -> Result<()>

Was termination successful? Returns a Result.

pub fn success(&self) -> bool

Was termination successful?

Signal termination is not considered a success, and success is defined as a zero exit status.

pub fn code(&self) -> Option<i32>

Returns the exit code of the process, if any.

In Unix terms the return value is the exit status: the value passed to exit, if the process finished by calling exit. Note that on Unix the exit status is truncated to 8 bits, and that values that didn’t come from a program’s call to exit may be invented by the runtime system (often, for example, 255, 254, 127 or 126).

This will return None if the process was terminated by a signal. ExitStatusExt is an extension trait for extracting any such signal, and other details, from the ExitStatus.

pub fn signal(&self) -> Option<i32>

If the process was terminated by a signal, returns that signal.

In other words, if WIFSIGNALED, this returns WTERMSIG.

pub fn core_dumped(&self) -> bool

If the process was terminated by a signal, says whether it dumped core.

pub fn stopped_signal(&self) -> Option<i32>

If the process was stopped by a signal, returns that signal.

In other words, if WIFSTOPPED, this returns WSTOPSIG. This is only possible if the status came from a wait system call which was passed WUNTRACED, and was then converted into an ExitStatus.

pub fn continued(&self) -> bool

Whether the process was continued from a stopped status.

Ie, WIFCONTINUED. This is only possible if the status came from a wait system call which was passed WCONTINUED, and was then converted into an ExitStatus.

pub fn into_raw(&self) -> c_int

Returns the underlying raw wait status.

The returned integer is a wait status, not an exit status.

Trait Implementations

impl Clone for ExitStatus

fn clone(&self) -> ExitStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExitStatus

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

Formats the value using the given formatter.

impl From<i32> for ExitStatus

Converts a raw c_int to a type-safe ExitStatus by wrapping it without copying.

fn from(a: c_int) -> ExitStatus

Converts to this type from the input type.

impl PartialEq for ExitStatus

fn eq(&self, other: &ExitStatus) -> 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.
