Struct RedisBackend 

pub struct RedisBackend { /* private fields */ }

Available on crate features memorydb and redis only.

Redis memory database backend.

Uses a ConnectionManager, which reconnects to Redis automatically, so the backend can be cloned and shared freely.

Implementations

impl RedisBackend

pub async fn new(dsn: &str) -> Result<Self>

Connect to Redis with a DSN like redis://user:pass@127.0.0.1:6379/0.

Trait Implementations

impl Clone for RedisBackend

fn clone(&self) -> RedisBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl MemoryDB for RedisBackend

fn set<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, value: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Set key to value without expiration.

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the value of key, or None if it does not exist or has expired.

fn get_del<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the value of key and delete it atomically.

fn get_ex<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, ttl: &'life2 Duration, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Get the value of key and reset its TTL to ttl.

fn set_ex<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, key: &'life1 str, value: &'life2 str, ttl: &'life3 Duration, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Set key to value with an expiration of ttl.

fn del<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete key. Returns whether the key existed.

fn expire<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, ttl: &'life2 Duration, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Set the TTL of key to ttl. Returns whether the key exists. A zero ttl deletes the key.

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

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

Remove all keys from the database.

fn keys<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get all keys matching the glob key pattern (e.g. prefix*).

fn dels<'life0, 'life1, 'async_trait>( &'life0 self, keys: &'life1 [String], ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete multiple keys. Returns the number of keys deleted.

fn ttl<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Duration>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the remaining TTL of key, or None if the key does not exist or has no TTL.
