Configuration for AdaptivePolicy.

Fields

target_hit_rate: f64

Desired cache hit rate as a fraction in (0.0, 1.0].

tolerance: f64

Half-width of the “good enough” band around target_hit_rate.

If the observed rate is within [target - tolerance, target + tolerance] no adjustment is made.

adjustment_interval: u64

Number of operations between adjustment evaluations.

min_capacity: usize

Minimum cache capacity the policy will ever recommend.

max_capacity: usize

Maximum cache capacity the policy will ever recommend.

growth_factor: f64

Multiplicative factor for capacity growth (e.g. 1.5 → +50%).

shrink_factor: f64

Multiplicative factor for capacity shrink (e.g. 0.75 → −25%).

ttl_extension: Duration

Duration added to TTL when the cache is under-performing.

ttl_reduction: Duration

Duration removed from TTL when the cache is over-provisioned.

window_size: usize

Number of recent observations kept in the rolling window.

Implementations

impl AdaptiveConfig

pub fn validate(&self) -> Result<(), AdaptiveError>

Validate the configuration, returning an error if any field is out of range.

Trait Implementations

impl Clone for AdaptiveConfig

fn clone(&self) -> AdaptiveConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdaptiveConfig

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

Formats the value using the given formatter.

impl Default for AdaptiveConfig

fn default() -> Self

Returns the “default value” for a type.
