free_port() hands out a port that is free when asked, not when soulfind binds it, and soulfind exits when the port has gone. The library harness also gave soulfind only five seconds and did not notice a child that had died, so either read as "no soulfind server" and failed the test. It now waits ten seconds like the CLI harness, never takes a child that has exited as up, and retries on a fresh port; the CLI harness gets the same retry. A listener that takes the port first can still answer before soulfind has got as far as binding, so the two library tests that bind listeners outside the server gate now take it too: while a soulfind starts, no other test in that binary binds anything.
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.
Usage
Add it to your Cargo.toml:
cargo add soulseek-rs-lib
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(())
}
ClientOperation is #[non_exhaustive]: every protocol message the client
learns to handle adds a variant, so match it with a wildcard arm. SharedFile
is too, so build it with the .. syntax rather than listing every field.
