Controls the behavior of a SigAction

Implementations

impl SaFlags

const SA_NOCLDSTOP: Self = _;

When catching a Signal::SIGCHLD signal, the signal will be generated only when a child process exits, not when a child process stops.

const SA_NOCLDWAIT: Self = _;

When catching a Signal::SIGCHLD signal, the system will not create zombie processes when children of the calling process exit.

const SA_NODEFER: Self = _;

Further occurrences of the delivered signal are not masked during the execution of the handler.

const SA_ONSTACK: Self = _;

The system will deliver the signal to the process on a signal stack, specified by each thread with sigaltstack(2).

const SA_RESETHAND: Self = _;

The handler is reset back to the default at the moment the signal is delivered.

const SA_RESTART: Self = _;

Requests that certain system calls restart if interrupted by this signal. See the man page for complete details.

const SA_SIGINFO: Self = _;

This flag is controlled internally by Nix.

impl SaFlags

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 SaFlags

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

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<SaFlags>

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.
