Struct AtomicData 

pub struct AtomicData { /* private fields */ }

Atomic<i64> storage — wraps a std::sync::atomic::AtomicI64 for the atomic operations exposed by the Atomic.load / store / fetch_add / fetch_sub / compare_exchange method surface.

i64-only at landing per the playbook’s typed-payload deferral precedent (W15-priority-queue i64-priority-only). A typed-payload Atomic<T> is a future Phase-2c amendment with measurement.

Memory ordering is SeqCst (sequential consistency) throughout — the simplest semantically-correct ordering. Relaxed-ordering optimizations are a measured follow-up.

Implementations

impl AtomicData

pub fn new(init: i64) -> Self

Build an AtomicData with initial value init.

pub fn load(&self) -> i64

Atomic load (SeqCst).

pub fn store(&self, v: i64)

Atomic store (SeqCst).

pub fn fetch_add(&self, delta: i64) -> i64

Atomic fetch-add (SeqCst). Returns the prior value.

pub fn fetch_sub(&self, delta: i64) -> i64

Atomic fetch-sub (SeqCst). Returns the prior value.

pub fn compare_exchange(&self, expected: i64, new_v: i64) -> i64

Atomic compare-exchange (SeqCst). Returns the prior value regardless of success — callers infer success by comparing to expected.

Trait Implementations

impl Debug for AtomicData

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

Formats the value using the given formatter.
