Trait AtomicPrimitive 

pub unsafe trait AtomicPrimitive:
    Sized
    + Copy
    + Sealed {
    type AtomicInner;
}
🔬This is a nightly-only experimental API. (atomic_internals)

A marker trait for primitive types which can be modified atomically.

This is an implementation detail for Atomic<T> which may disappear or be replaced at any time.

Safety

Types implementing this trait must be primitives that can be modified atomically.

The associated Self::AtomicInner type must have the same size and bit validity as Self, but may have a higher alignment requirement, so the following transmutes are sound:

  • &mut Self::AtomicInner as &mut Self
  • Self as Self::AtomicInner or the reverse

Required Associated Types

Source
type AtomicInner
🔬This is a nightly-only experimental API. (atomic_internals)

Temporary implementation detail.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
