Function std::intrinsics::volatile_set_memory[][src]

pub unsafe extern "rust-intrinsic" fn volatile_set_memory<T>(
    dst: *mut T,
    val: u8,
    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.memset.p0i8.* 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.
