Trait AtomicLoad 

pub trait AtomicLoad: Primitive {
    // Required method
    unsafe fn atomic_load(
        src: *const MaybeUninit<Self>,
        order: Ordering,
    ) -> MaybeUninit<Self>;
}

Atomic load.

This trait is sealed and cannot be implemented for types outside of atomic-maybe-uninit.

Required Methods

unsafe fn atomic_load( src: *const MaybeUninit<Self>, order: Ordering, ) -> MaybeUninit<Self>

Loads a value from src.

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

Safety

Behavior is undefined if any of the following conditions are violated:

• src must be valid for reads.
• src must be aligned to size_of::<MaybeUninit<T>>() (note that on some platforms this can be bigger than align_of::<MaybeUninit<T>>()).
• order must be SeqCst, Acquire, or Relaxed.
• You must adhere to the Memory model for atomic accesses. In particular, it is not allowed to mix conflicting atomic and non-atomic accesses, or atomic accesses of different sizes, without synchronization.

Compatibility with read-only memory applies only to relaxed operations with a register or smaller width. See the “Atomic accesses to read-only memory” section in the core::sync::atomic docs for more.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
