Struct CacheLineAtomicBool 

#[repr(align(64))]
pub struct CacheLineAtomicBool {
    pub value: AtomicBool,
}

A single-bit flag padded to a full cache line (64 bytes) to prevent false sharing when an array of flags is accessed concurrently from different cores.

Used for the per-core has_work array: the sender core sets the destination core’s flag after a ring push; the drain task reads it to skip ring scanning when there is no pending inter-core traffic.

Fields

value: AtomicBool

Implementations

impl CacheLineAtomicBool

pub const fn new(v: bool) -> Self

pub fn signal(&self)

Signal that work is available (Release so ring push is visible to reader).

pub fn set_true(&self)

Set the flag to true with Release ordering.

pub fn set_false(&self)

Set the flag to false with Release ordering.

pub fn is_set(&self) -> bool

Load the flag with Acquire ordering (paired with signal).

pub fn take(&self) -> bool

Atomically read and clear the flag (AcqRel).
