Implementations

impl IPCAtomicU64

pub fn open(path: &Path, initial_value: u64) -> Result<Self, IPCAtomicError>

pub fn atomic(&self) -> &AtomicU64

pub fn load(&self) -> u64

pub fn store(&self, val: u64)

pub fn inc(&self) -> u64

pub fn fetch_update( &self, f: impl FnMut(u64) -> Option<u64>, ) -> Result<u64, u64>

Returns the last-seen value from reading when f returns None as Err; returns Ok with the new value if f returned Some (and storing succeeded–if it failed, it retries until f returns None).
