🔬 This is a nightly-only experimental API. (
intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Equivalent to the appropriate
llvm.memmove.p0i8.0i8.* intrinsic, with
a size of
size_of::<T>() and an alignment of
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.
