pub struct AtomicI8(/* private fields */);
Expand description
Mock implementation of std::sync::atomic::AtomicI8
.
NOTE: Unlike std::sync::atomic::AtomicI8
, this type has a different in-memory representation than i8
.
Implementations§
source§impl AtomicI8
impl AtomicI8
sourcepub fn with_mut<R>(&mut self, f: impl FnOnce(&mut i8) -> R) -> R
pub fn with_mut<R>(&mut self, f: impl FnOnce(&mut i8) -> R) -> R
Get access to a mutable reference to the inner value.
sourcepub unsafe fn unsync_load(&self) -> i8
pub unsafe fn unsync_load(&self) -> i8
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.
sourcepub fn into_inner(self) -> i8
pub fn into_inner(self) -> i8
Consumes the atomic and returns the contained value.
sourcepub fn swap(&self, val: i8, order: Ordering) -> i8
pub fn swap(&self, val: i8, order: Ordering) -> i8
Stores a value into the atomic integer, returning the previous value.
sourcepub fn compare_and_swap(&self, current: i8, new: i8, order: Ordering) -> i8
pub fn compare_and_swap(&self, current: i8, new: i8, order: Ordering) -> i8
Stores a value into the atomic integer if the current value is the same as the current
value.
sourcepub fn compare_exchange(
&self,
current: i8,
new: i8,
success: Ordering,
failure: Ordering
) -> Result<i8, i8>
pub fn compare_exchange( &self, current: i8, new: i8, success: Ordering, failure: Ordering ) -> Result<i8, i8>
Stores a value into the atomic if the current value is the same as the current
value.
sourcepub fn compare_exchange_weak(
&self,
current: i8,
new: i8,
success: Ordering,
failure: Ordering
) -> Result<i8, i8>
pub fn compare_exchange_weak( &self, current: i8, new: i8, success: Ordering, failure: Ordering ) -> Result<i8, i8>
Stores a value into the atomic if the current value is the same as the current value.
sourcepub fn fetch_add(&self, val: i8, order: Ordering) -> i8
pub fn fetch_add(&self, val: i8, order: Ordering) -> i8
Adds to the current value, returning the previous value.
sourcepub fn fetch_sub(&self, val: i8, order: Ordering) -> i8
pub fn fetch_sub(&self, val: i8, order: Ordering) -> i8
Subtracts from the current value, returning the previous value.
sourcepub fn fetch_nand(&self, val: i8, order: Ordering) -> i8
pub fn fetch_nand(&self, val: i8, order: Ordering) -> i8
Bitwise “nand” with the current value.
sourcepub fn fetch_max(&self, val: i8, order: Ordering) -> i8
pub fn fetch_max(&self, val: i8, order: Ordering) -> i8
Stores the maximum of the current and provided value, returning the previous value
sourcepub fn fetch_min(&self, val: i8, order: Ordering) -> i8
pub fn fetch_min(&self, val: i8, order: Ordering) -> i8
Stores the minimum of the current and provided value, returning the previous value
