Struct MemoryCacheManager 

pub struct MemoryCacheManager { /* private fields */ }

A Memory-based implementation of the CacheManager trait using Moka.

Implementations

impl MemoryCacheManager

pub fn new(prefix: String, options: MemoryCacheOptions) -> Self

Creates a new Memory cache manager with Moka configuration.

impl MemoryCacheManager

pub async fn delete(&mut self, key: &str) -> Result<bool>

Delete a key from the cache.

pub async fn get_many(&mut self, keys: &[&str]) -> Result<Vec<Option<String>>>

Get multiple keys at once.

pub async fn set_many( &mut self, pairs: &[(&str, &str)], _ttl_seconds: u64, ) -> Result<()>

Set multiple key-value pairs at once.

pub async fn get_all_entries(&self) -> Vec<(String, String, Option<Duration>)>

Get all entries from the cache as (key, value, ttl) tuples. Returns entries without the prefix.

Note: Moka doesn’t support per-entry TTL tracking, so this returns the cache’s default TTL for all entries. When syncing to another cache system, this means all entries will get the same TTL, not their remaining time.
