Struct LruConfig 

pub struct LruConfig {
    pub counter_bits: BitCount,
    pub aging_strategy: LruAgingStrategy,
    pub starting_value: u32,
    pub remove_on_zero: bool,
    pub increment: u32,
}

Configuration for the LRU field.

Used to define memory used by the LRU field, also affecting its maximum value.

Examples

use cuckoo_clock::config::LruConfig;

let ttl_config = LruConfig {
    counter_bits: 5.try_into()?,
    ..Default::default()
};

Fields

counter_bits: BitCount

Number of bits used to represent the LRU counter. Larger bit counts allow more values to be represented, allowing items to “accumulate” higher use counts, which will take longer to age.

aging_strategy: LruAgingStrategy

The strategy to use when aging LRU counters.

starting_value: u32

The starting value for LRU counter to use.

remove_on_zero: bool

If set to true, items that already have a 0 counter value will be removed at scan time.

increment: u32

Increment to add to LRU counter on each insert and lookup.

Trait Implementations

impl Clone for LruConfig

fn clone(&self) -> LruConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LruConfig

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

Formats the value using the given formatter.

impl Default for LruConfig

fn default() -> Self

Returns the “default value” for a type.

impl Eq for LruConfig

impl PartialEq for LruConfig

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