Struct CachingAspect 

pub struct CachingAspect { /* private fields */ }

Generic caching aspect with TTL support.

Example

use aspect_std::CachingAspect;
use aspect_macros::aspect;
use std::time::Duration;

let cache = CachingAspect::new().with_ttl(Duration::from_secs(60));

#[aspect(cache.clone())]
fn expensive_query(id: u64) -> Result<String, String> {
    // Expensive operation - will be cached
    Ok(format!("Result for {}", id))
}

Implementations

impl CachingAspect

pub fn new() -> Self

Create a new caching aspect with no size limit.

pub fn with_max_size(self, max_size: usize) -> Self

fn around( &self, pjp: ProceedingJoinPoint<'_>, ) -> Result<Box<dyn Any>, AspectError>

Advice that wraps the entire target function execution.

fn before(&self, _ctx: &JoinPoint)

Advice executed before the target function runs.

fn after(&self, _ctx: &JoinPoint, _result: &(dyn Any + 'static))

Advice executed after the target function completes successfully.

fn after_error(&self, _ctx: &JoinPoint, _error: &AspectError)

Advice executed when the target function encounters an error.

impl Clone for CachingAspect

fn clone(&self) -> CachingAspect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for CachingAspect

fn default() -> Self
