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?;

Feature Flags
tls
: Enables therustls
-based TLS connection. Not enabled by default.tls-roots
: Adds system trust roots torustls
-based TLS connection using therustls-native-certs
crate. Not enabled by default.pub-response-field
: Exposes structs used to create regularetcd-client
responses including internal protobuf representations. Useful for mocking. Not enabled by default.tls-openssl
: Enables theopenssl
-based TLS connections. This would make your binary dynamically link tolibssl
.tls-openssl-vendored
: Liketls-openssl
, however compile openssl from source code and statically link to it.
Test
We test this library with etcd 3.5.
Notes that we use a fixed etcd
server URI (localhost:2379) to connect to etcd server.
Rust version requirements
The minimum supported version is 1.56. The current etcd-client
version is not guaranteed to build on Rust versions earlier than the minimum supported version.
