Struct FastPathProcessor 

pub struct FastPathProcessor { /* private fields */ }

Fast-path request processor for high RPS scenarios

Implements aggressive caching and optimization strategies for frequently accessed resources. Uses in-memory caches with configurable eviction policies and request pattern analysis for optimal performance.

Implementations

impl FastPathProcessor

pub fn new(router: Arc<Router>, metrics: Arc<PerformanceMetrics>) -> Self

Create a new fast-path processor

Arguments

• router - The application router for processing requests
• metrics - Metrics collector for performance tracking

pub async fn process(&self, request: Request) -> Result<Response>

Process a request using fast-path optimizations

Attempts to serve requests from cache when possible, falling back to full router processing for cache misses. Automatically populates the cache with cacheable responses based on HTTP headers.

Arguments

• request - The HTTP request to process

Returns

The HTTP response, either from cache or freshly generated

Performance Characteristics

• Cache hits: ~1-2μs response time
• Cache misses: Full router processing time + cache population overhead
• Memory usage: Bounded by cache size limit (default 1000 entries)

pub fn clear_cache(&self)

Clear the response cache

Removes all cached responses. Useful for cache invalidation scenarios or memory management in long-running servers.
