core::intrinsics::atomic_xsub_acq - Rust
Description: API documentation for the Rust `atomic_xsub_acq` fn in crate `core`.
Keywords: rust, rustlang, rust-lang, atomic_xsub_acq

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

    pub unsafe extern "rust-intrinsic" fn atomic_xsub_acq<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

Subtract from the current value, returning the previous value. The stabilized version of this intrinsic is available on the `std::sync::atomic` types via the `fetch_sub` method by passing `Ordering::Acquire` as the `order`. For example, `AtomicIsize::fetch_sub`.

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
