Example of publish and subscription using Redis and Rusg Language.
[dependencies] tokio = { version = "", features = ["full"] } redis = "" uuid = { version = "0.8.2", features = ["v4"] } serde_json = "" serde = {version = "", features = ["derive"]}
- tokio is used in this case to create an async main method and to access the mutithread features.
- In the case of serde, whose features are used to serialize and deserialize objects, it's important to add the derive features, otherwise it will not be possible to add the Serialize and Deserialize traits on the Derive attribute, in this case, on Message struct, as follows:
#[derive(Debug, Serialize, Deserialize)] pub struct Message { pub id: String, pub channel: String, pub payload: Order }
When you don't add the derive feature, the following error is shown: cannot find derive macro Serialize in this scope.
