Function std::intrinsics::volatile_copy_memory [−][src]
pub unsafe extern "rust-intrinsic" fn volatile_copy_memory<T>(
dst: *mut T,
src: *const T,
count: usize
)
🔬 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
Expand description
Equivalent to the appropriate llvm.memmove.p0i8.0i8.*
intrinsic, with
a size of count * size_of::<T>()
and an alignment of
min_align_of::<T>()
The volatile parameter is set to true
, so it will not be optimized out
unless size is equal to zero.
This intrinsic does not have a stable counterpart.
