# Function bitflags::__core::intrinsics::atomic_singlethreadfence [−] [src]

    pub unsafe extern "rust-intrinsic" fn atomic_singlethreadfence()

Unstable (`core_intrinsics`)

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

A compiler-only memory barrier.

Memory accesses will never be reordered across this barrier by the compiler, but no instructions will be emitted for it. This is appropriate for operations on the same thread that may be preempted, such as when interacting with signal handlers.

## 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`)
