Implementations

impl AtomicU16_le

pub const fn new(value: u16) -> Self

Returns a AtomicU16_le containing value.

impl AtomicU16_le

pub fn compare_exchange( &self, current: u16, new: u16, success: Ordering, failure: Ordering, ) -> Result<u16, u16>

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

See AtomicU16::compare_exchange for more information.

pub fn compare_exchange_weak( &self, current: u16, new: u16, success: Ordering, failure: Ordering, ) -> Result<u16, u16>

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

See AtomicU16::compare_exchange_weak for more information.

pub fn fetch_add(&self, val: u16, order: Ordering) -> u16

Adds to the current value, returning the previous value.

Because addition is not an endian-agnostic operation, fetch_add is implemented in terms of AtomicU16::compare_exchange_weak on big-endian targets. This may result in worse performance on those targets.

See AtomicU16::fetch_add for more information.

pub fn fetch_and(&self, val: u16, order: Ordering) -> u16

Bitwise “and” with the current value.

See AtomicU16::fetch_and for more information.

pub fn fetch_max(&self, val: u16, order: Ordering) -> u16

Maximum with the current value.

Because maximum is not an endian-agnostic operation, fetch_max is implemented in terms of AtomicU16::compare_exchange_weak on big-endian targets. This may result in worse performance on those targets.

See AtomicU16::fetch_max for more information.

pub fn fetch_min(&self, val: u16, order: Ordering) -> u16

Minimum with the current value.

Because minimum is not an endian-agnostic operation, fetch_min is implemented in terms of AtomicU16::compare_exchange_weak on big-endian targets. This may result in worse performance on those targets.

See AtomicU16::fetch_min for more information.

pub fn fetch_nand(&self, val: u16, order: Ordering) -> u16

Bitwise “nand” with the current value.

See AtomicU16::fetch_nand for more information.

pub fn fetch_or(&self, val: u16, order: Ordering) -> u16

Bitwise “or” with the current value.

See AtomicU16::fetch_or for more information.

pub fn fetch_sub(&self, val: u16, order: Ordering) -> u16

Subtracts from the current value, returning the previous value.

Because subtraction is not an endian-agnostic operation, fetch_sub is implemented in terms of AtomicU16::compare_exchange_weak on big-endian targets. This may result in worse performance on those targets.

See AtomicU16::fetch_sub for more information.

pub fn fetch_update<F: FnMut(u16) -> Option<u16>>( &self, set_order: Ordering, fetch_order: Ordering, f: F, ) -> Result<u16, u16>

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).

See AtomicU16::fetch_update for more information.

pub fn fetch_xor(&self, val: u16, order: Ordering) -> u16

Bitwise “xor” with the current value.

See AtomicU16::fetch_xor for more information.

pub fn into_inner(self) -> u16

Consumes the atomic and returns the contained value.

See AtomicU16::into_inner for more information.

pub fn load(&self, order: Ordering) -> u16

Loads a value from the atomic integer.

See AtomicU16::load for more information.

pub fn store(&self, val: u16, order: Ordering)

Stores a value into the atomic integer.

See AtomicU16::store for more information.

pub fn swap(&self, val: u16, order: Ordering) -> u16

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

See AtomicU16::swap for more information.
