Function prefetch_write_data

pub unsafe extern "rust-intrinsic" fn prefetch_write_data<T>(
    data: *const T,
    locality: i32,
)

🔬This is a nightly-only experimental API. (core_intrinsics)

The prefetch intrinsic is a hint to the code generator to insert a prefetch instruction if supported; otherwise, it is a no-op. Prefetches have no effect on the behavior of the program but can change its performance characteristics.

The locality argument must be a constant integer and is a temporal locality specifier ranging from (0) - no locality, to (3) - extremely local keep in cache.

This intrinsic does not have a stable counterpart.
