Struct SemanticCacheConfig 

pub struct SemanticCacheConfig {
    pub threshold: f32,
    pub max_entries: usize,
    pub ttl: Option<Duration>,
}

Semantic cache configuration.

Fields

threshold: f32

Minimum cosine similarity for a semantic hit. Conservative default: a too-low threshold serves semantically-nearbut-different queries.

max_entries: usize

Max entries; the oldest are evicted FIFO (same policy as lc-agents’ MemoryCache).

ttl: Option<Duration>

Optional TTL: entries older than this are treated as misses (corpus updates invalidate results; pair with invalidate() for explicit invalidation).

Implementations

impl SemanticCacheConfig

pub fn new() -> Self

Creates a config with defaults.

pub fn with_threshold(self, threshold: f32) -> Self

Sets the semantic-hit threshold.

pub fn with_max_entries(self, max_entries: usize) -> Self

Sets the max entry count (FIFO eviction).

pub fn with_ttl(self, ttl: Option<Duration>) -> Self

Sets an optional TTL.

Trait Implementations

fn clone(&self) -> SemanticCacheConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticCacheConfig

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

Formats the value using the given formatter.

impl Default for SemanticCacheConfig

fn default() -> Self

Returns the “default value” for a type.
