CacheLineAtomicBool

Struct CacheLineAtomicBool 

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

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§

Source§

impl CacheLineAtomicBool

Source

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

Source

pub fn signal(&self)

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

Source

pub fn set_true(&self)

Set the flag to true with Release ordering.

Source

pub fn set_false(&self)

Set the flag to false with Release ordering.

Source

pub fn is_set(&self) -> bool

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

Source

pub fn take(&self) -> bool

Atomically read and clear the flag (AcqRel).
