Struct SignalSet 

pub struct SignalSet { /* private fields */ }

A bit-packed set of Signal values.

SignalSet is Copy and const-constructible. The recommended constructors are SignalSet::graceful (the default for long-running services) and SignalSet::standard.

Implementations

impl SignalSet

pub const fn empty() -> Self

Empty set.

pub const fn all() -> Self

All defined variants enabled. Inert variants on the current platform are still represented but ignored by install.

pub const fn graceful() -> Self

The recommended default: Terminate | Interrupt | Hangup.

pub const fn standard() -> Self

Maximum graceful coverage: Terminate | Interrupt | Quit | Hangup.

pub const fn with(self, sig: Signal) -> Self

Return a copy of self with sig enabled.

pub const fn without(self, sig: Signal) -> Self

Return a copy of self with sig disabled.

pub const fn contains(self, sig: Signal) -> bool

Check whether sig is enabled.

pub const fn is_empty(self) -> bool

true if the set has no signals enabled.

pub const fn len(self) -> usize

Number of signals enabled in the set.

pub const fn iter(&self) -> SignalSetIter

Iterate the enabled signals in canonical Signal::ALL order.

Trait Implementations

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 Default for SignalSet

fn default() -> Self

Returns the “default value” for a type.

impl IntoIterator for SignalSet

type Item = Signal

The type of the elements being iterated over.

type IntoIter = SignalSetIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

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.
