Struct Config

Source
pub struct Config<TMsg, TMessageChannel>
where TMessageChannel: IMessageChannel,
{ pub url: Url, pub subscription_channel: TMessageChannel, pub fn_input: fn(&Message<TMsg>) -> Result<Option<Vec<ConfigFnInputItem<TMessageChannel>>>, Error>, pub fn_output: fn(&str) -> Result<Option<Vec<Message<TMsg>>>, Error>, }

Fields§

§url: Url

Адрес сервера Redis

§Примеры

url: Url::parse("redis://redis:6379").unwrap(),
§subscription_channel: TMessageChannel

Название канала для подписки Pub/Sub и хеша, где хранятся сообщения

§Примеры

subscription_channel: ExampleMessageChannel::Output,
§fn_input: fn(&Message<TMsg>) -> Result<Option<Vec<ConfigFnInputItem<TMessageChannel>>>, Error>

Функция преобразования входящего потока сообщений в данные для отправки в Redis

§Примеры

§Заглушка

fn_input: |_| Ok(None),

§Сериализация в json

fn_input: |msg: &Message<Custom>| {
    let channel = ExampleMessageChannel::Output;
    let key = msg.key.clone();
    let value = msg.serialize()?;
    Ok(Some(vec![cmp_redis_client::ConfigFnInputItem {
        channel,
        key,
        value,
    }]))
},

Возможность рассылки в несколько каналов нужна для организации роутинга сообщений

§fn_output: fn(&str) -> Result<Option<Vec<Message<TMsg>>>, Error>

Функция преобразования данных из Redis в исходящий поток сообщений

§Примеры

§Заглушка

fn_output: |_| Ok(None),

§Десериализация из json

fn_output: |text: &str| {
    let msg = Message::deserialize(text)?;
    Ok(Some(vec![msg]))
},
