Struct ExitStatus 

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

Exit status of a process.

This is an opaque type that wraps the platform’s native exit status representation. Use the provided methods to query the exit status.

On Unix, the raw value is the status from waitpid(). On Windows, it is the exit code from GetExitCodeProcess().

Implementations

impl ExitStatus

pub fn code(&self) -> Option<u32>

Returns the exit code if the process exited normally.

On Unix, this returns Some only if the process exited voluntarily (not killed by a signal).

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

Returns the signal number if the process was killed by a signal.

impl ExitStatus

pub fn success(&self) -> bool

True if the exit status of the process is 0.

pub fn is_killed_by(&self, signum: i32) -> bool

True if the subprocess was killed by a signal with the specified number.

Always returns false on Windows.

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<'_>) -> Result

Formats the value using the given formatter.

impl Display for ExitStatus

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

Formats the value using the given formatter.

impl Hash for ExitStatus

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
