Crate aspect_std 

aspect-std

Standard aspects library providing common, production-ready aspects.

This crate provides a collection of reusable aspects for common cross-cutting concerns:

• Logging: Structured logging with configurable levels
• Timing: Performance monitoring with statistics
• Caching: Generic memoization with TTL
• Metrics: Counters, gauges, and histograms
• Rate Limiting: Token bucket algorithm for throttling
• Circuit Breaker: Fault tolerance and failure prevention
• Authorization: Role-based access control
• Validation: Pre/post condition checking

Quick Start

use aspect_std::prelude::*;
use aspect_macros::aspect;

// Use the standard logging aspect
#[aspect(LoggingAspect::new())]
fn my_function(x: i32) -> i32 {
    x * 2
}
