Example

Call echo stored procedure

run tarantool

cd test-tarantool;tarantool init-tarantool.lua

Lua stored procedure:

function test(a,b)
   return a,b,11
end

Rust client :


println!("Connect to tarantool and call simple stored procedure!");
let mut rt = Runtime::new().unwrap();

let addr = "127.0.0.1:3301".parse().unwrap();
let client = ClientConfig::new(addr, "rust", "rust").build();

let response_future = client.call_fn2("test", &("param11", "param12") , &2)
    .and_then(|response| {
        let res : ((String,String), (u64,), (Option<u64>,)) = response.decode_trio()?;
        Ok(res)
    }) ;

match rt.block_on(response_future) {
    Err(e) => println!("err={:?}", e),
    Ok(res) => println!("stored procedure response ={:?}", res)
}

Output :

Connect to tarantool and call simple stored procedure!
stored procedure response =(("param11", "param12"), (2,), (Some(11),))
