Advice to pass to FileIoExt::advise.

Variants

Normal = 0

No advice; default heuristics apply.

Sequential = 2

Data will be accessed sequentially at ascending offsets.

Random = 1

Data will be accessed with an irregular access pattern.

WillNeed = 3

Data will be accessed soon.

DontNeed = 4

Data will not be accessed soon.

NoReuse = 5

Data will be accessed exactly once.

Trait Implementations

impl Debug for Advice

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

Formats the value using the given formatter.

impl Hash for Advice

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Advice

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Advice

impl StructuralEq for Advice

impl StructuralPartialEq for Advice
