Struct loom::sync::atomic::AtomicI16

source ·
pub struct AtomicI16(/* private fields */);
Expand description

Mock implementation of std::sync::atomic::AtomicI16.

NOTE: Unlike std::sync::atomic::AtomicI16, this type has a different in-memory representation than i16.

Implementations§

source§

impl AtomicI16

source

pub fn new(v: i16) -> Self

Creates a new instance of AtomicI16.

source

pub fn with_mut<R>(&mut self, f: impl FnOnce(&mut i16) -> R) -> R

Get access to a mutable reference to the inner value.

source

pub unsafe fn unsync_load(&self) -> i16

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.

source

pub fn into_inner(self) -> i16

Consumes the atomic and returns the contained value.

source

pub fn load(&self, order: Ordering) -> i16

Loads a value from the atomic integer.

source

pub fn store(&self, val: i16, order: Ordering)

Stores a value into the atomic integer.

source

pub fn swap(&self, val: i16, order: Ordering) -> i16

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

source

pub fn compare_and_swap(&self, current: i16, new: i16, order: Ordering) -> i16

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

source

pub fn compare_exchange( &self, current: i16, new: i16, success: Ordering, failure: Ordering ) -> Result<i16, i16>

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

source

pub fn compare_exchange_weak( &self, current: i16, new: i16, success: Ordering, failure: Ordering ) -> Result<i16, i16>

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

source

pub fn fetch_add(&self, val: i16, order: Ordering) -> i16

Adds to the current value, returning the previous value.

source

pub fn fetch_sub(&self, val: i16, order: Ordering) -> i16

Subtracts from the current value, returning the previous value.

source

pub fn fetch_and(&self, val: i16, order: Ordering) -> i16

Bitwise “and” with the current value.

source

pub fn fetch_nand(&self, val: i16, order: Ordering) -> i16

Bitwise “nand” with the current value.

source

pub fn fetch_or(&self, val: i16, order: Ordering) -> i16

Bitwise “or” with the current value.

source

pub fn fetch_xor(&self, val: i16, order: Ordering) -> i16

Bitwise “xor” with the current value.

source

pub fn fetch_max(&self, val: i16, order: Ordering) -> i16

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

source

pub fn fetch_min(&self, val: i16, order: Ordering) -> i16

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

source

pub fn fetch_update<F>( &self, set_order: Ordering, fetch_order: Ordering, f: F ) -> Result<i16, i16>where F: FnMut(i16) -> Option<i16>,

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).
