When I use documents and examples, I find it can't help me about rust-ipfs-api HOT 2 CLOSED

use http::Uri;
use ipfs_api_backend_hyper::{IpfsApi, IpfsClient, TryFromUri};
use std::io::Cursor;

#[tokio::main]
async fn main() {
        let uri = "http://192.168.1.80:5001/".parse::<Uri>().unwrap();
        let client = IpfsClient::build_with_base_uri(uri);
        match client.version().await {
                Ok(version) => eprintln!("version: {:?}", version.version),
                Err(e) => eprintln!("error getting version: {}", e),
        };
        match client.pubsub_pub("test", Cursor::new("TEST!")).await {
                Ok(_) => println!("OK!"),
                Err(e) => println!("error: {}", e),
        };
}
