Struct SigSet

pub struct SigSet { /* private fields */ }

Specifies a set of Signals that may be blocked, waited for, etc.

Implementations

impl SigSet

pub fn all() -> SigSet

Initialize to include all signals.

pub fn empty() -> SigSet

Initialize to include nothing.

pub fn add(&mut self, signal: Signal)

Add the specified signal to the set.

pub fn clear(&mut self)

Remove all signals from this set.

pub fn remove(&mut self, signal: Signal)

Remove the specified signal from this set.

pub fn contains(&self, signal: Signal) -> bool

Return whether this set includes the specified signal.

pub fn iter(&self) -> SigSetIter<'_>

Returns an iterator that yields the signals contained in this set.

pub fn thread_get_mask() -> Result<SigSet>

Gets the currently blocked (masked) set of signals for the calling thread.

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

Sets the set of signals as the signal mask for the calling thread.

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

Adds the set of signals to the signal mask for the calling thread.

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

Removes the set of signals from the signal mask for the calling thread.

pub fn thread_swap_mask(&self, how: SigmaskHow) -> Result<SigSet>

Sets the set of signals as the signal mask, and returns the old mask.

pub fn wait(&self) -> Result<Signal>

Suspends execution of the calling thread until one of the signals in the signal mask becomes pending, and returns the accepted signal.

pub unsafe fn from_sigset_t_unchecked(sigset: sigset_t) -> SigSet

Converts a libc::sigset_t object to a SigSet without checking whether the libc::sigset_t is already initialized.

Safety

The sigset passed in must be a valid an initialized libc::sigset_t by calling either sigemptyset(3) or sigfillset(3). Otherwise, the results are undefined.

Trait Implementations

impl AsRef<sigset_t> for SigSet

fn as_ref(&self) -> &sigset_t

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SigSet

fn clone(&self) -> SigSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SigSet

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

Formats the value using the given formatter.

impl Extend<Signal> for SigSet

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = Signal>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl FromIterator<Signal> for SigSet

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = Signal>,

Creates a value from an iterator.

impl Hash for SigSet

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<'a> IntoIterator for &'a SigSet

type Item = Signal

The type of the elements being iterated over.

type IntoIter = SigSetIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for SigSet

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