#[repr(u8)]
pub enum Advice {
    Normal = 0,
    Sequential = 1,

File or memory access pattern advisory information.

Variants

Normal = 0

The application has no advice to give on its behavior with respect to the specified data.

Sequential = 1

The application expects to access the specified data sequentially from lower offsets to higher offsets.

Random = 2

The application expects to access the specified data in a random order.

WillNeed = 3

The application expects to access the specified data in the near future.

DontNeed = 4

The application expects that it will not access the specified data in the near future.

NoReuse = 5

The application expects to access the specified data once and then not reuse it thereafter.

Trait Implementations

impl Clone for Advice

fn clone(&self) -> Advice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Advice

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

Formats the value using the given formatter.

impl Ord for Advice

fn cmp(&self, other: &Advice) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Advice

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

impl PartialOrd for Advice

fn partial_cmp(&self, other: &Advice) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
