Struct RedisCache 

pub struct RedisCache { /* private fields */ }

Redis cache backend with a short-lived local memory fallback.

Implementations

impl RedisCache

pub async fn new(url: &str, default_ttl: u64) -> Result<Self>

Creates a Redis cache from a Redis URL and default TTL in seconds.

Errors

Returns CacheError when the URL is invalid or the initial Redis connection fails.

pub async fn from_credentials( base_url: &str, username: Option<&str>, password: Option<&str>, default_ttl: u64, ) -> Result<Self>

Creates a Redis cache from a base URL and raw credentials.

Errors

Returns CacheError when credential injection or URL parsing fails, or Redis cannot be reached during initialization.

Trait Implementations

impl CacheBackend for RedisCache

fn backend_name(&self) -> &'static str

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Performs a lightweight backend health check.
