Enum MemAdvice 

#[repr(u64)]
pub enum MemAdvice {
    Normal = 0,
    Random = 1_023,
    Sequential = 1_047_552,
}

Memory access pattern advice.

This encodes a subset of POSIX.1-2001 madvise flags, and is intending to be a workable cross platform abstraction. In particular, the values do not correspond to any libc or other lib constants, and are arranged in ascending order of minimal to maximum priority in the presence of concurrent interest in the same region.

Variants

Normal = 0

Random = 1_023

Sequential = 1_047_552

Trait Implementations

impl Clone for MemAdvice

fn clone(&self) -> MemAdvice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemAdvice

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

Formats the value using the given formatter.

impl From<u64> for MemAdvice

fn from(v: u64) -> Self

Converts to this type from the input type.

impl Ord for MemAdvice

fn cmp(&self, other: &MemAdvice) -> 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 MemAdvice

fn eq(&self, other: &MemAdvice) -> 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 MemAdvice

fn partial_cmp(&self, other: &MemAdvice) -> 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.
