Rust EventStore TCP Client.

Talk and exchange ideas in our dedicated Discord Server

State of implemented features

• Can connect to GetEventStore >=4.* servers.
• Connection health tracking.
• Operation timeout detection and retry.
• Write events.
• Read events (including $all stream).
• Read/Write stream metadata.
• Transactions.
• Delete stream.
• Volatile Subscriptions.
• Catchup Subscriptions.
• Persistent Subscriptions.
• Support connection to server clusters. (through gossip, using custom DNS server is still TODO)
• Support SSL connection.

Example

#[macro_use]
extern crate serde_json;

use eventstore::{ Connection, EventData };
use futures::Future;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let addr = "127.0.0.1:1113".parse()?;
    let connection = Connection::builder()
        .single_node_connection(addr)
        .await;

    // It is not mandatory to use JSON as a data format however GetEventStore
    // provides great additional value if you do so.
    let payload = json!({
        "is_rust_a_nice_language": true,
    });

    let event = EventData::json("language-poll", payload)?;

    let result = connection
        .write_events("language-stream")
        .push_event(event)
        .execute()
        .await?;

    // Do something productive with the result.
    println!("{:?}", result);

    Ok(())
}

Notes

That library was tested on Linux and OSX.
