Implementations

impl RedisCacheDatabase

pub async fn new( trader_id: TraderId, instance_id: UUID4, config: CacheConfig, ) -> Result<Self>

Creates a new RedisCacheDatabase instance for the given trader_id, instance_id, and config.

Errors

Returns an error if:

• The database configuration is missing in config.
• Establishing the Redis connection fails.
• The command processing task cannot be spawned.

pub const fn get_encoding(&self) -> SerializationEncoding

pub fn get_trader_key(&self) -> &str

pub fn close(&mut self)

pub async fn flushdb(&mut self)

pub async fn keys(&mut self, pattern: &str) -> Result<Vec<String>>

Retrieves all keys matching the given pattern from Redis for this trader.

Errors

Returns an error if the underlying Redis scan operation fails.

pub async fn read(&mut self, key: &str) -> Result<Vec<Bytes>>

Reads the value(s) associated with key for this trader from Redis.

Errors

Returns an error if the underlying Redis read operation fails.

pub fn insert(&mut self, key: String, payload: Option<Vec<Bytes>>) -> Result<()>

Sends an insert command for key with optional payload to Redis via the background task.

Errors

Base class

type ThreadChecker = SendablePyClass<RedisCacheDatabase>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable
