CacheStore Trait

A trait for implementing cache storage backends. Provides key-value caching operations with optional TTL.

Methods

• get: Retrieves a value by key
• set: Stores a value with optional expiration
• delete: Removes a value by key

Required Methods

fn get(&self, key: &str) -> DataFuture<'_, Result<Option<String>, DataError>>

Retrieves a cached value by key.

Returns None if the key doesn’t exist or has expired.

fn set( &self, key: &str, value: &str, ttl_seconds: Option<u64>, ) -> DataFuture<'_, Result<(), DataError>>

Stores a value in the cache.

Arguments

• key: The cache key
• value: The value to store
• ttl_seconds: Optional expiration time in seconds

fn delete(&self, key: &str) -> DataFuture<'_, Result<(), DataError>>

Removes a value from the cache.
