Struct `WaitPidFlag`

#[repr(transparent)]
pub struct WaitPidFlag(/* private field */);

Controls the behavior of waitpid.

Implementations

`impl WaitPidFlag`

const fn empty() -> Self

Get a flags value with all bits unset.

const fn all() -> Self

Get a flags value with all known bits set.

const fn bits(&self) -> c_int

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

const fn from_bits(bits: c_int) -> Option<Self>

Convert from a bits value.

This method will return None if any unknown bits are set.

const fn from_bits_truncate(bits: c_int) -> Self

Convert from a bits value, unsetting any unknown bits.

const fn from_bits_retain(bits: c_int) -> Self

Convert from a bits value exactly.

fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn't correspond to any named flag.

const fn is_empty(&self) -> bool

Whether all bits in self are unset.

const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

const fn intersects(&self, other: Self) -> bool

Whether any set bits in other are also set in self.

const fn contains(&self, other: Self) -> bool

Whether all set bits in other are also set in self.

fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in self and other.

fn remove(&mut self, other: Self)

The intersection of self with the complement of other (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won't truncate other, but the ! operator will.

fn toggle(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in self and other.

fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

const fn intersection(self, other: Self) -> Self

The bitwise and (&) of the bits in self and other.

const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in self and other.

const fn difference(self, other: Self) -> Self

The intersection of self with the complement of other (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won't truncate other, but the ! operator will.

const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in self and other.

const fn complement(self) -> Self

The bitwise negation (!) of the bits in self, truncating the result.

`impl WaitPidFlag`

const fn iter(&self) -> Iter<WaitPidFlag>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

const fn iter_names(&self) -> IterNames<WaitPidFlag>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.

`impl WaitPidFlag`

const WNOHANG: Self = _;: Do not block when there are no processes wishing to report status.
const WUNTRACED: Self = _;: Report the status of selected processes which are stopped due to a SIGTTIN, SIGTTOU, SIGTSTP, or SIGSTOP signal.
const WEXITED: Self = _;: Report the status of selected processes which have terminated.
const WCONTINUED: Self = _;: Report the status of selected processes that have continued from a job control stop by receiving a SIGCONT signal.
const WSTOPPED: Self = _;: An alias for WUNTRACED.
const WNOWAIT: Self = _;: Don't reap, just poll status.
const __WNOTHREAD: Self = _;: Don't wait on children of other threads in this group
const __WALL: Self = _;: Wait on all children, regardless of type
const __WCLONE: Self = _;: Wait for "clone" children only.
