Struct Slot 

pub struct Slot<T: Copy> { /* private fields */ }

A value that can be loaded and stored without locking.

Loads and a store can run concurrently. There may be up to Self::MAX_READERS_COUNT concurrent loads but only single concurrent store allowed. You can think of slot as of SPMC atomic varible but for non-atomic types.

Implemented using a triple-buffer.

Implementations

impl<T: Copy> Slot<T>

pub const MAX_READERS_COUNT: usize = State::MAX_READERS_COUNT

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

pub fn load(&self) -> T

On success returns stored value.

• If there is no concurrent load takes place then the most recent value is returned
• If there are concurring loads then the same value is returned by all of them.

pub fn store(&self, value: T) -> Result<(), SlotStoreError>
