Enum MemoryAdviceOutcome 

pub enum MemoryAdviceOutcome {
    Applied,
    SkippedEmpty,
    Unsupported,
}

What became of one MemoryAdvice request.

Advice cannot change artifact bytes or correctness. Unsupported platforms retain the safe owned-byte fallback and report that they did not make an OS request instead of pretending a Windows PrefetchVirtualMemory policy was implemented and tested when it was not.

Variants

Applied

The native madvise request succeeded.

SkippedEmpty

The mapping is empty, so there is no range for the kernel to advise.

Unsupported

This build or platform deliberately has no native advisory implementation.
