Struct AtomicOptionRefArray

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

An array of references in which elements may be updated and retrieved atomically.

This is a Rust interpretation of AtomicReferenceArray from Java.

Implementations

impl<T> AtomicOptionRefArray<T>

pub fn new(len: usize) -> Self

Constructs a new array with the specified length. All values will be None.

pub fn new_with<U: IntoOptionArc<T>>(len: usize, f: impl Fn(usize) -> U) -> Self

Constructs a new array with the specified length. Uses the given function to construct each value.

pub fn len(&self) -> usize

Returns the number of elements in the array.

pub fn is_empty(&self) -> bool

Returns true if the array has a length of 0.

pub fn load(&self, index: usize) -> Option<Arc<T>>

Loads and returns a reference to an value at the given position or None if the value at the index is not set.

Panics if index is out of bounds.

pub fn store(&self, index: usize, value: impl IntoOptionArc<T>)

Stores the value at the given position.

Panics if index is out of bounds.

pub fn swap(&self, index: usize, value: impl IntoOptionArc<T>) -> Option<Arc<T>>

Swaps the value at the given position, returning the previous value.

Panics if index is out of bounds.
