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

    pub unsafe extern "rust-intrinsic" fn atomic_xchg_relaxed<T>(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

Stores the value at the specified memory location, returning the old value. The stabilized version of this intrinsic is available on the `std::sync::atomic` types via the `swap` method by passing `Ordering::Relaxed` as the `order`. For example, `AtomicBool::swap`.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
