Expand description

Use Redis as session storage backend.

    use actix_web::cookie::Key;

    // The secret key would usually be read from a configuration file/environment variables.
    fn get_secret_key() -> Key {
        // [...]
    }

    async fn main() -> std::io::Result<()> {
        let secret_key = get_secret_key();

## Implementation notes

`RedisActorSessionStore` leverages `actix-redis`’s `RedisActor` implementation - each thread worker gets its own connection to Redis.

### Limitations

`RedisActorSessionStore` does not currently support establishing authenticated connections to Redis. Use `RedisSessionStore` if you need TLS support.

## Implementations§

source §

### impl RedisActorSessionStore

source

#### pub fn builder<S: Into<String>>(
connection_string: S
) -> RedisActorSessionStoreBuilder

A fluent API to configure `RedisActorSessionStore`.

It takes as input the only required input to create a new instance of `RedisActorSessionStore`—a connection string for Redis.

source

#### pub fn new<S: Into<String>>(connection_string: S) -> RedisActorSessionStore

Create a new instance of `RedisActorSessionStore` using the default configuration. It takes as input the only required input to create a new instance of `RedisActorSessionStore` - a connection string for Redis.
