Struct AtomicConstPtr 

pub struct AtomicConstPtr<T> { /* private fields */ }

An atomic pointer type which operates on *const T.

This type provides a typed wrapper around [AtomicPtr] that enforces *const T invariants throughout its API, avoiding the need for cast_mut() or manual pointer qualification casts at call sites.

Implementations

impl<T> AtomicConstPtr<T>

pub const fn new(ptr: *const T) -> Self

Creates a new AtomicConstPtr initialized with ptr.

pub fn load(&self, order: Ordering) -> *const T

Loads a value from the pointer with the specified memory ordering.

pub fn store(&self, ptr: *const T, order: Ordering)

Stores a value into the pointer with the specified memory ordering.

pub fn swap(&self, ptr: *const T, order: Ordering) -> *const T

Stores a value into the pointer, returning the previous value.

pub fn compare_exchange( &self, current: *const T, new: *const T, success: Ordering, failure: Ordering, ) -> Result<*const T, *const T>

Stores a value into the pointer if the current value is the same as current.

The return value is a result indicating whether the new value was written and containing the previous value.

pub fn compare_exchange_weak( &self, current: *const T, new: *const T, success: Ordering, failure: Ordering, ) -> Result<*const T, *const T>

Stores a value into the pointer if the current value is the same as current.

Unlike [compare_exchange], this function is allowed to spuriously fail.

pub fn try_update<F>( &self, set_order: Ordering, fetch_order: Ordering, f: F, ) -> Result<*const T, *const T>

where F: FnMut(*const T) -> Option<*const T>,

Fetches the value, and applies a function to it that returns an optional new value. Returns a Result of Ok(previous_value) if the function returned Some(_), else Err(previous_value).

pub fn into_inner(self) -> *const T

Consumes the atomic pointer, returning the underlying raw pointer.
