Struct TrackerConfig

Source

pub struct TrackerConfig {
    pub max_records: usize,

    pub cold_threshold: f64,

Expand description

Configuration parameters that govern tracker behaviour.

Fields§

§max_records: usize

Maximum number of records held at any time. When exceeded, AccessTracker::enforce_capacity evicts the coldest entries.

§recency_weight: f64

Multiplicative weight applied to the recency component of the score. Higher values reward recently-accessed blocks more strongly.

§decay_factor: f64

Time-based decay applied per second of idle time. Larger values make scores fall faster as blocks sit unused.

§hot_threshold: f64

Score threshold above which a block is classified as hot.

§cold_threshold: f64

Score threshold below which a block is classified as cold.
