# Function core::intrinsics::atomic_and_relaxed
[−][src]

    pub unsafe extern "rust-intrinsic" fn atomic_and_relaxed<T: Copy>(
        dst: *mut T,
        src: T
    ) -> T

🔬 This is a nightly-only experimental API. (`core_intrinsics`)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

This is supported on non-crate feature `miri-test-libstd` or `test` or `doctest` only.
Expand description

Bitwise and with the current value, returning the previous value.

The stabilized version of this intrinsic is available on the `atomic` types via the `fetch_and` method by passing `Ordering::Relaxed` as the `order`. For example, `AtomicBool::fetch_and`.
