Struct SignalSet 

pub struct SignalSet { /* private fields */ }

A set of signals represented as a bitmask.

Uses atomic operations for lock-free signal delivery.

Implementations

impl SignalSet

pub const fn new() -> Self

Create an empty signal set.

pub const fn from_mask(mask: u64) -> Self

Create a signal set from a raw mask value.

pub fn add(&self, signal: Signal)

Add a signal to the set.

pub fn remove(&self, signal: Signal)

Remove a signal from the set.

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

Check if a signal is in the set.

pub fn is_empty(&self) -> bool

Check if the set is empty.

pub fn get_mask(&self) -> u64

Get the raw mask value.

pub fn set_mask(&self, mask: u64)

Set the raw mask value.

pub fn clear(&self)

Clear all signals.

pub fn next_pending(&self) -> Option<Signal>

Get the next pending signal (lowest numbered).

pub fn unblocked(&self, blocked: &SignalSet) -> u64

Get signals that are in self but not in blocked.

pub fn consume_one_unblocked(&self, blocked: &SignalSet) -> Option<Signal>

Atomically consume one pending unblocked signal (CAS loop).

Trait Implementations

impl Clone for SignalSet

fn clone(&self) -> Self

Performs the clone operation.

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

Performs copy-assignment from source.

impl Debug for SignalSet

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