Struct StateSlotHandle 

pub struct StateSlotHandle { /* private fields */ }

Lock-free handle to a 32-bit state slot or runtime knob shared between an instrumented driver and a StateBank.

Implementations

impl StateSlotHandle

pub fn new(initial: u32) -> Self

Creates a new slot handle initialized to initial.

pub fn load(&self) -> u32

Loads the current 32-bit value with sequentially consistent ordering.

pub fn store(&self, value: u32)

Stores a new 32-bit value with sequentially consistent ordering.

pub fn fetch_add(&self, delta: u32) -> u32

Atomically adds delta to the current value, returning the previous value.

pub fn fetch_or(&self, mask: u32) -> u32

Atomically bitwise-ORs mask into the current value, returning the previous value.

pub fn fetch_and(&self, mask: u32) -> u32

Atomically bitwise-ANDs mask into the current value, returning the previous value.

pub fn as_atomic(&self) -> &AtomicU32

Returns a reference to the underlying AtomicU32.
