Struct SignalSet

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

A group of multiple different Signals

This is a Newtype for libc::sigset_t and the related functions used to manipulate a signal set.

Implementations

impl SignalSet

pub fn fill() -> Result<SignalSet>

Initialize a set to contain all signals

pub fn empty() -> Result<SignalSet>

Initialize a set to contain no signals

Note that this function will never fail, since sigemptyset() has no errors defined.

pub fn add(&mut self, signal: Signal) -> Result<()>

Add signal to a set

pub fn remove(&mut self, signal: Signal) -> Result<()>

Remove signal from a set

Trait Implementations

impl AsRef<sigset_t> for SignalSet

fn as_ref(&self) -> &sigset_t

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

impl Clone for SignalSet

fn clone(&self) -> SignalSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignalSet

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

Formats the value using the given formatter.

impl From<&[Signal]> for SignalSet

fn from(signals: &[Signal]) -> Self

Return a SignalSet from a slice of Signals

Note that this conversion is save since SignalSet::empty() never fails and the slice of Signals contains valid signals only, ever.

impl PartialEq for SignalSet

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