Enum WaitStatus 

pub enum WaitStatus {
    Exited(i32),
    Signaled(i32),
    Stopped(i32),
    Continued,
}

Status returned by waitpid describing how a child changed state.

Variants

Exited(i32)

Child exited normally with the given status code.

Signaled(i32)

Child was terminated by a signal.

Stopped(i32)

Child was stopped by a signal (only with WUNTRACED).

Continued

Child was resumed by SIGCONT (only with WCONTINUED).

Implementations

impl WaitStatus

pub fn to_raw(self) -> i32

Encode the status as a raw i32 matching POSIX wstatus layout.

• Exited: (code & 0xFF) << 8
• Signaled: signum & 0x7F
• Stopped: 0x7F | (signum << 8)
• Continued: 0xFFFF

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.
