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

Examples can be found in examples.

Feature Flags

  • tls: Enables the rustls-based TLS connection. Not enabled by default.
  • tls-roots: Adds system trust roots to rustls-based TLS connection using the rustls-native-certs crate. Not enabled by default.
  • pub-response-field: Exposes structs used to create regular etcd-client responses including internal protobuf representations. Useful for mocking. Not enabled by default.

Test

We test this library with etcd 3.4.

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

Rust version requirements

The minimum supported version is 1.45. The current etcd-client version is not guaranteed to build on Rust versions earlier than the minimum supported version.
