Struct EventFlagSet 

pub struct EventFlagSet { /* private fields */ }

Event flag set: logical flags + wakeup mechanism for state sets.

Separates logical state (AtomicBool per flag) from wakeup delivery (Notify per state set). Setting a flag wakes all state sets.

Implementations

impl EventFlagSet

pub fn new( num_flags: usize, sync_map: Vec<Vec<usize>>, ss_wakeups: Vec<Arc<Notify>>, ) -> Self

pub fn set(&self, ef_id: usize)

Set a flag and wake all state sets.

pub fn test(&self, ef_id: usize) -> bool

Test a flag (non-destructive).

pub fn clear(&self, ef_id: usize) -> bool

Clear a flag. Returns the previous value.

pub fn test_and_clear(&self, ef_id: usize) -> bool

Test and clear atomically. Returns the previous value.

pub fn synced_channels(&self, ef_id: usize) -> &[usize]

Get the channel ids synced to a given event flag.

pub fn num_flags(&self) -> usize
