Michel de Graaf 543e9ee865 fix(peer): wait for the transfer token before the download lookup
The listener looked the download up immediately after the PeerInit(F),
but the 4-byte transfer token routinely arrives in a separate TCP
segment, so every firewalled peer download failed with "Download info
missing". Wait for the token within the handshake deadline and give up
on the connection when it never arrives.

Also quiets the dispatcher's unhandled-message-code log to debug; the
server routinely sends codes the library doesn't implement.

soulseek-rs-lib

A Rust library for implementing the Soulseek peer-to-peer protocol.

Website: https://re-invention.nl/soulseek-rs/

About

This library provides the core functionality for interacting with the Soulseek network. It can be used to build custom Soulseek clients or bots.

Usage

Add this to your Cargo.toml:

[dependencies]
soulseek-rs-lib = "8"

Example

Simple Usage

use soulseek_rs::Client;
use std::time::Duration;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create and connect to Soulseek server
    let mut client = Client::new("username", "password");

    client.connect()?;
    client.login()?;

    // Search for files
    let results = client.search("Alex Kassian lifestream", Duration::from_secs(10))?;

    // Download first available file
    if let Some(result) = results.iter().find(|r| !r.files.is_empty()) {
        let file = &result.files[0];
        let (_download, status) = client.download(
            file.name.clone(),
            file.username.clone(),
            file.size,
            "~/Downloads".to_string(),
        )?;

        // `download` returns as soon as the request is queued: the transfer is
        // finished when the channel says so, not when this call returns.
        for update in status {
            println!("{}: {update:?}", file.name);
        }
    }

    Ok(())
}

Advanced Configuration

use soulseek_rs::{Client, ClientSettings, PeerAddress};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create client with custom settings
    let settings = ClientSettings {
        server_address: PeerAddress::new("server.slsknet.org".to_string(), 2416),
        enable_listen: true,
        listen_port: 3000,
        ..ClientSettings::new("username", "password")
    };

    let mut client = Client::with_settings(settings);
    client.connect()?;
    client.login()?;

    Ok(())
}

Asking about a peer

The server-backed lookups are request/poll pairs: you ask, then read the answer once it lands. request_user_info clears any previous answer first, so the loop below observes this request rather than the last one.

use soulseek_rs::Client;
use std::thread::sleep;
use std::time::{Duration, Instant};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = Client::new("username", "password");
    client.connect()?;
    client.login()?;

    client.request_user_info("someuser")?;

    let deadline = Instant::now() + Duration::from_secs(10);
    while Instant::now() < deadline {
        if let Some(info) = client.user_info("someuser") {
            // Presence and stats are separate replies, so each is an Option:
            // a reply that never arrived is None, not "offline" or "shares nothing".
            println!("{:?} {:?}", info.presence, info.stats);
            break;
        }
        sleep(Duration::from_millis(100));
    }

    // Room membership is kept current from join and leave events.
    println!("{:?}", client.room_members("lobby"));

    Ok(())
}

ServerMessage and ClientOperation are #[non_exhaustive]: every protocol message the client learns to handle adds a variant, so match them with a wildcard arm.
