Struct AtomicWifiState

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

A wrapper around WifiState which can be safely shared between threads.

This type uses an AtomicUsize to store the enum value.

Implementations

impl AtomicWifiState

pub const fn new(v: WifiState) -> AtomicWifiState

Creates a new atomic WifiState.

pub fn into_inner(self) -> WifiState

Consumes the atomic and returns the contained value.

This is safe because passing self by value guarantees that no other threads are concurrently accessing the atomic data.

pub fn set(&mut self, v: WifiState)

Sets the value of the atomic without performing an atomic operation.

This is safe because the mutable reference guarantees that no other threads are concurrently accessing the atomic data.

pub fn get(&mut self) -> WifiState

Gets the value of the atomic without performing an atomic operation.

This is safe because the mutable reference guarantees that no other threads are concurrently accessing the atomic data.

pub fn swap_mut(&mut self, v: WifiState) -> WifiState

Stores a value into the atomic, returning the previous value, without performing an atomic operation.

This is safe because the mutable reference guarantees that no other threads are concurrently accessing the atomic data.

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

Loads a value from the atomic.

load takes an Ordering argument which describes the memory ordering of this operation. Possible values are SeqCst, Acquire and Relaxed.

Panics

Panics if order is Release or AcqRel.

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

Stores a value into the atomic.

store takes an Ordering argument which describes the memory ordering of this operation. Possible values are SeqCst, Release and Relaxed.

Panics

Panics if order is Acquire or AcqRel.

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

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

swap takes an Ordering argument which describes the memory ordering of this operation. All ordering modes are possible. Note that using Acquire makes the store part of this operation Relaxed, and using Release makes the load part Relaxed.

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

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

The return value is a result indicating whether the new value was written and containing the previous value. On success this value is guaranteed to be equal to current.

compare_exchange takes two Ordering arguments to describe the memory ordering of this operation. The first describes the required ordering if the operation succeeds while the second describes the required ordering when the operation fails. Using Acquire as success ordering makes the store part of this operation Relaxed, and using Release makes the successful load Relaxed. The failure ordering can only be SeqCst, Acquire or Relaxed and must be equivalent to or weaker than the success ordering.

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

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

Unlike compare_exchange, this function is allowed to spuriously fail even when the comparison succeeds, which can result in more efficient code on some platforms. The return value is a result indicating whether the new value was written and containing the previous value.

compare_exchange_weak takes two Ordering arguments to describe the memory ordering of this operation. The first describes the required ordering if the operation succeeds while the second describes the required ordering when the operation fails. Using Acquire as success ordering makes the store part of this operation Relaxed, and using Release makes the successful load Relaxed. The failure ordering can only be SeqCst, Acquire or Relaxed and must be equivalent to or weaker than the success ordering.
