Implementations

impl LockFreeUtils

pub fn atomic_update<F>(atomic: &AtomicU64, updater: F) -> u64

where F: FnMut(u64) -> u64,

Perform an atomic read-modify-write operation with retry.

pub fn atomic_increment_bounded( atomic: &AtomicU64, max_value: u64, ) -> Result<u64, u64>

Perform an atomic increment with overflow protection.

pub fn atomic_decrement_bounded( atomic: &AtomicU64, min_value: u64, ) -> Result<u64, u64>

Perform an atomic decrement with underflow protection.

pub fn double_checked_init<T, F>( atomic_flag: &AtomicUsize, initializer: F, ) -> bool

where F: FnOnce() -> T,

Double-checked locking pattern helper.
