Struct CachedCorrelation 

pub struct CachedCorrelation { /* private fields */ }

Cached correlation computer with performance tracking

OPT-001: Caches correlation results to avoid redundant computation

Implementations

impl CachedCorrelation

pub fn new() -> Self

Create cached correlation with default capacity (1000 entries, 5 min TTL)

pub fn with_capacity(capacity: usize) -> Self

Create cached correlation with custom capacity

pub fn correlate( &mut self, x: &Vector<f32>, y: &Vector<f32>, x_idx: usize, y_idx: usize, ) -> Result<f32>

Compute correlation with caching

Cache key is based on vector indices (assumes stable vector ordering)

pub fn correlation_matrix( &mut self, vectors: &[Vector<f32>], ) -> Result<Vec<Vec<f32>>>

Compute correlation matrix for multiple vectors

pub fn stats(&self) -> &PerfStats

Get performance statistics

pub fn cache_hit_rate(&self) -> f64

Get cache hit rate

pub fn cache_stats(&self) -> (u64, u64)

Get cache statistics

pub fn clear_cache(&mut self)

Clear cache

Trait Implementations

impl Default for CachedCorrelation

fn default() -> Self

Returns the “default value” for a type.
