Struct CachePerformanceAnalyzer 

pub struct CachePerformanceAnalyzer;

Utility for computing cache effectiveness metrics from session events.

This is a stateless analyzer — call CachePerformanceAnalyzer::analyze with any slice of events to get a CacheMetrics snapshot.

Example

use adk_runner::CachePerformanceAnalyzer;

let metrics = CachePerformanceAnalyzer::analyze(&events);
println!("Hit ratio: {:.1}%, Utilization: {:.1}%",
    metrics.cache_hit_ratio, metrics.cache_utilization_ratio);

Implementations

impl CachePerformanceAnalyzer

pub fn analyze(events: &[Event]) -> CacheMetrics

Analyze cache performance from a slice of events.

Iterates over all events, extracts usage_metadata from LLM responses, and computes aggregate cache metrics. Events without usage_metadata are skipped. An empty slice returns zeroed metrics.
