Enum IoProbeMode 

pub enum IoProbeMode {
    Buffered,
    Seq,
    NoBuf,
    NoBufOverlapped,
}

I/O strategy to measure for one $MFT read pass (ADR-0011).

Variants

Buffered

The production strategy: buffered synchronous reads.

Seq

Buffered + FILE_FLAG_SEQUENTIAL_SCAN cache hint.

NoBuf

FILE_FLAG_NO_BUFFERING, synchronous (no cache-manager copy).

NoBufOverlapped

FILE_FLAG_NO_BUFFERING + FILE_FLAG_OVERLAPPED with queue_depth reads outstanding — tests whether sequential multiplexing helps (parallel random reads are known to serialize in the kernel).

Trait Implementations

impl Clone for IoProbeMode

fn clone(&self) -> IoProbeMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IoProbeMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for IoProbeMode

fn eq(&self, other: &IoProbeMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
