Struct L2Cache 

pub struct L2Cache { /* private fields */ }

L2 cache implementation using Redis

Implementations

impl L2Cache

pub async fn new(metrics: CacheMetrics) -> Result<Self, L2Error>

Create a new L2 cache with default configuration

pub async fn with_config( config: L2Config, metrics: CacheMetrics, ) -> Result<Self, L2Error>

Create a new L2 cache with custom configuration

pub async fn get(&self, key: &str) -> Result<Option<CachedResponse>, L2Error>

Get a value from the cache

Performance

Target: 1-2ms (network round-trip)

pub async fn set( &self, key: String, value: CachedResponse, ) -> Result<(), L2Error>

Set a value in the cache

Performance

Target: 1-2ms (async, non-blocking) This is designed to be called asynchronously without blocking the main request

pub async fn set_with_ttl( &self, key: String, value: CachedResponse, ttl_seconds: u64, ) -> Result<(), L2Error>

Set a value in the cache with custom TTL

pub async fn remove(&self, key: &str) -> Result<(), L2Error>

Remove a value from the cache

pub async fn clear(&self) -> Result<(), L2Error>

Clear all cache entries (use with caution!)

pub async fn health_check(&self) -> bool

Check if Redis connection is healthy

pub async fn approximate_size(&self) -> Result<usize, L2Error>

Get the current size of the cache (approximate)

pub fn config(&self) -> &L2Config

Get cache configuration

Trait Implementations

impl Clone for L2Cache

fn clone(&self) -> L2Cache

Returns a duplicate of the value.

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

Performs copy-assignment from source.
