Example​

Via Builder​

use anyhow::Result;
use opendal::services::Etcd;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Etcd::default();

    // this will build a Operator accessing etcd which runs on http://127.0.0.1:2379
    let op: Operator = Operator::new(builder)?.finish();
    Ok(())
}

Via Config​

use anyhow::Result;
use opendal::Operator;
use opendal::Scheme;
use std::collections::HashMap;

#[tokio::main]
async fn main() -> Result<()> {
    let mut map = HashMap::new();
    map.insert("root".to_string(), "/path/to/dir".to_string());
    map.insert("endpoints".to_string(), "http://127.0.0.1:2379".to_string());
    map.insert("username".to_string(), "your_username".to_string());
    map.insert("password".to_string(), "your_password".to_string());

    let op: Operator = Operator::via_map(Scheme::Etcd, map)?;
    Ok(())
}
