示例

[dependencies]
nostr_rust = "*"

然后是代码

use std::{
    str::FromStr,
    sync::{Arc, Mutex},
    thread,
};

use nostr_rust::{nostr_client::Client, req::ReqFilter, Identity, Message, events::extract_events_ws, utils::parse_content_tags};

fn handle_message(relay_url: &String, message: &Message) -> Result<(), String> {
    println!("Received message from {}: {:?}", relay_url, message);

    let events = extract_events_ws(message);
    println!("Events: {:?}", events);

    Ok(())
}

fn main() {
    let my_identity =
        Identity::from_str("your private key as hex string")
            .unwrap();

    let nostr_client = Arc::new(Mutex::new(
        Client::new(vec!["wss://relay.nostr.info"]).unwrap(),
    ));

    // Run a new thread to handle messages
    let nostr_clone = nostr_client.clone();
    let handle_thread = thread::spawn(move || {
        println!("Listening...");
        let events = nostr_clone.lock().unwrap().next_data().unwrap();

        for (relay_url, message) in events.iter() {
            handle_message(relay_url, message).unwrap();
        }
    });

    // Change metadata
    nostr_client
        .lock()
        .unwrap()
        .set_metadata(
            &my_identity,
            Some("Rust Nostr Client test account"),
            Some("Hello Nostr! #5"),
            None,
            None,
            0,
        )
        .unwrap();

    // Subscribe to my last text note
    let subscription_id = nostr_client
        .lock()
        .unwrap()
        .subscribe(vec![ReqFilter {
            ids: None,
            authors: Some(vec![
                "884704bd421721e292edbff42eb77547fe115c6ff9825b08fc366be4cd69e9f6".to_string(),
            ]),
            kinds: None,
            e: None,
            p: None,
            since: None,
            until: None,
            limit: Some(1),
        }])
        .unwrap();

    // Unsubscribe
    nostr_client
        .lock()
        .unwrap()
        .unsubscribe(&subscription_id)
        .unwrap();

    // You can use the parse content tags method to get the content and the tags from a string
    // let tags = parse_content_tags("hello #world", vec![], Some(nostr_rust::DEFAULT_HASHTAG), true, true);
    // assert_eq!(tags.content, "hello #world");
    //  assert_eq!(tags.tags, vec![vec!["t", "world"]]);

    // Publish a text note
    nostr_client
        .lock()
        .unwrap()
        .publish_text_note(&my_identity, "Hello Nostr! :)", &[], 0)
        .unwrap();

    // Publish a proof of work text note with a difficulty target of 15
    nostr_client
        .lock()
        .unwrap()
        .publish_text_note(&my_identity, "Hello Nostr! :)", &[], 15)
        .unwrap();

    // Wait for the thread to finish
    handle_thread.join().unwrap();
}

## Async feature

If you want to use the async version of the client, you can enable the `async` feature:

```toml
[dependencies]
nostr_rust = { version = "*", features = ["async"] }
