You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: health_resp_cloud.rs
    path of file: ./repos/dystopia/dytp-component/src
    
    the code of the file until where you have to start completion: use crate::node::Node;
use semver::Version;
use serde_derive::Serialize;

// TODO:
// May be it's too heavy to return every nodes every times.
// We need pagination or other logics to limit number of return nodes.
#[derive(Debug, Serialize)]
pub struct HealthRespCloud {
    version: V
    
    fn from(n: &[u8]) -> HealthRespCloud {
        let version_nodes = std::str::from_utf8(n)
            .unwrap()
            .split(" ")
            .collect::<Vec<&str>>();

        if version_nodes.len() % 3 != 1 {
            log::error!("invalid response={:?}", version_nodes);

            panic!();
        }

        let version = version_nodes[0].parse().unwrap();
        let nodes_len = (version_nodes.len() - 1) / 3;
        let mut nodes = Vec::new();

        for idx in 0..nodes_len {
            let addr = version_nodes[idx * 3 + 1].parse().unwrap();
            let state = version_nodes[idx * 3 + 2].parse().unwrap();
            let version = version_nodes[idx * 3 + 3].parse().unwrap();

            nodes.push(Node {
                addr,
                state,
                version,
            });
        }

        HealthRespCloud { version, nodes }
    }
