Enum TouchHint 

pub enum TouchHint {
    Never,
    Eager,
    Lazy,
}

Hint for when to touch (prewarm) memory pages during mapping creation.

Variants

Never

Don’t touch pages during creation (default).

Eager

Eagerly touch all pages during creation to prewarm page tables and improve first-access latency. Useful for benchmarking scenarios where you want consistent timing without page fault overhead.

Lazy

Touch pages lazily on first access (same as Never for now).

Trait Implementations

impl Clone for TouchHint

fn clone(&self) -> TouchHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TouchHint

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

Formats the value using the given formatter.

impl Default for TouchHint

fn default() -> TouchHint

Returns the “default value” for a type.

impl PartialEq for TouchHint

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