An etcd v3 API client for Rust. It provides asynchronous client backed by tokio and tonic.

• etcd API v3
• asynchronous

• KV
• Watch
• Lease
• Lock
• Auth
• Maintenance
• Cluster
• Election

Add this to your Cargo.toml:

[dependencies]
etcd-client = "0.2"
tokio = { version = "0.2", features = ["full"] }

To get started using etcd-client:

use etcd_client::{Client, Error};

#[tokio::main]
async fn main() -> Result<(), Error> {
    let mut client = Client::connect(["localhost:2379"], None).await?;
    // put kv
    client.put("foo", "bar", None).await?;
    // get kv
    let resp = client.get("foo", None).await?;
    if let Some(kv) = resp.kvs().first() {
        println!("Get kv: {{{}: {}}}", kv.key_str()?, kv.value_str()?);
    }

    Ok(())
}

Examples can be found in examples.

We test this library using etcd 3.4.

Notes that we use a fixed etcd server URI (localhost:2379) to connect to etcd server.

etcd-client works on rust 1.39 and above as it requires support for the async_await feature.
