Struct CacheConfig 

pub struct CacheConfig {
    pub max_entries: usize,
    pub ttl: Duration,
    pub similarity_threshold: f32,
    pub enable_approximate_matching: bool,
}

Configuration for query result caching.

Fields

max_entries: usize

Maximum number of cached queries.

ttl: Duration

Time-to-live for cached results.

similarity_threshold: f32

Tolerance for approximate query matching (0.0 = exact match).

enable_approximate_matching: bool

Whether to enable approximate matching.

Implementations

impl CacheConfig

pub fn high_hit_rate() -> Self

Create a config optimized for high hit rate (more entries, longer TTL).

pub fn low_memory() -> Self

Create a config optimized for low memory (fewer entries, shorter TTL).

pub fn exact_match_only() -> Self

Create a config with exact matching only.
