Official Rust EventStoreDB rust gRPC gRPC Client.
EventStoreDB is the event-native database, where business events are immutably stored and streamed. Designed for event-sourced, event-driven, and microservices architectures.
This client is compatible with version 20.6.1 upwards and works on Linux, MacOS and Windows.
Server setup instructions can be found here EventStoreDB Docs, follow the docker setup for the simplest configuration.
use eventstore::{ Client, EventData };
use serde::{Serialize, Deserialize};
#[derive(Serialize, Deserialize, Debug)]
struct Foo {
is_rust_a_nice_language: bool,
}
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Creates a client settings for a single node configuration.
let settings = "esdb://admin:changeit@localhost:2113".parse()?;
let client = Client::new(settings)?;
let payload = Foo {
is_rust_a_nice_language: true,
};
// It is not mandatory to use JSON as a data format however EventStoreDB
// provides great additional value if you do so.
let evt = EventData::json("language-poll", &payload)?;
client
.append_to_stream("language-stream", &Default::default(), evt)
.await?;
let mut stream = client
.read_stream("language-stream", &Default::default())
.await?;
while let Some(event) = stream.next().await? {
let event = event.get_original_event()
.as_json::<Foo>()?;
// Do something productive with the result.
println!("{:?}", event);
}
Ok(())

Bear in mind that this client is not yet properly documented. We are working hard on a new version of the documentation.
