Struct loom::sync::atomic::AtomicI64

pub struct AtomicI64(/* private fields */);

Mock implementation of std::sync::atomic::AtomicI64.

NOTE: Unlike std::sync::atomic::AtomicI64, this type has a different in-memory representation than i64.

Implementations

impl AtomicI64

pub fn new(v: i64) -> Self

Creates a new instance of AtomicI64.

pub fn with_mut<R>(&mut self, f: impl FnOnce(&mut i64) -> R) -> R

Get access to a mutable reference to the inner value.

pub unsafe fn unsync_load(&self) -> i64

Load the value without any synchronization.

Safety

An unsynchronized atomic load technically always has undefined behavior. However, if the atomic value is not currently visible by other threads, this should always be equivalent to a non-atomic load of an un-shared integer value.

pub fn into_inner(self) -> i64

Consumes the atomic and returns the contained value.

pub fn load(&self, order: Ordering) -> i64

Loads a value from the atomic integer.

pub fn store(&self, val: i64, order: Ordering)

Stores a value into the atomic integer.

pub fn swap(&self, val: i64, order: Ordering) -> i64

Stores a value into the atomic integer, returning the previous value.

pub fn compare_and_swap(&self, current: i64, new: i64, order: Ordering) -> i64

Stores a value into the atomic integer if the current value is the same as the current value.

pub fn compare_exchange( &self, current: i64, new: i64, success: Ordering, failure: Ordering ) -> Result<i64, i64>

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

pub fn compare_exchange_weak( &self, current: i64, new: i64, success: Ordering, failure: Ordering ) -> Result<i64, i64>

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

pub fn fetch_add(&self, val: i64, order: Ordering) -> i64

Adds to the current value, returning the previous value.

pub fn fetch_sub(&self, val: i64, order: Ordering) -> i64

Subtracts from the current value, returning the previous value.

pub fn fetch_and(&self, val: i64, order: Ordering) -> i64

Bitwise “and” with the current value.

pub fn fetch_nand(&self, val: i64, order: Ordering) -> i64

Bitwise “nand” with the current value.

pub fn fetch_or(&self, val: i64, order: Ordering) -> i64

Bitwise “or” with the current value.

pub fn fetch_xor(&self, val: i64, order: Ordering) -> i64

Bitwise “xor” with the current value.

pub fn fetch_max(&self, val: i64, order: Ordering) -> i64

Stores the maximum of the current and provided value, returning the previous value

pub fn fetch_min(&self, val: i64, order: Ordering) -> i64

Stores the minimum of the current and provided value, returning the previous value

pub fn fetch_update<F>( &self, set_order: Ordering, fetch_order: Ordering, f: F ) -> Result<i64, i64>where F: FnMut(i64) -> Option<i64>,

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).
