Enum SlruSegment 

pub enum SlruSegment {
    Probationary,
    Protected,
}

Segment location within an SLRU cache.

SLRU divides the cache into two segments:

• Probationary: New entries start here
• Protected: Entries promoted after multiple accesses

Items in the protected segment are shielded from one-time scans.

Variants

Probationary

Entry is in the probationary segment (initial placement). Items here are candidates for eviction when the cache is full.

Protected

Entry is in the protected segment (promoted after repeated access). Items here are protected from eviction by one-time scans.

Trait Implementations

impl Clone for SlruSegment

fn clone(&self) -> SlruSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlruSegment

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

Formats the value using the given formatter.

impl Default for SlruSegment

fn default() -> SlruSegment

Returns the “default value” for a type.

impl PartialEq for SlruSegment

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