seedlink-rs

Pure Rust SeedLink client and server. Zero unsafe, zero C dependency.

Sister project of miniseed-rs.

Crates

Quick Start

use seedlink_rs_client::SeedLinkClient;

#[tokio::main]
async fn main() -> seedlink_rs_client::Result<()> {
    let mut client = SeedLinkClient::connect("rtserve.iris.washington.edu:18000").await?;
    client.station("ANMO", "IU").await?;
    client.select("BHZ").await?;
    client.data().await?;
    client.end_stream().await?;

    while let Some(frame) = client.next_frame().await? {
        println!("seq={}, payload={} bytes", frame.sequence(), frame.payload().len());
    }
    Ok(())
}

Status

seedlink-rs-protocol and seedlink-rs-client are published and functional. Tested against IRIS (rtserve.iris.washington.edu:18000) with 154 tests passing.

What works today

• SeedLink v3 and v4 protocol negotiation
• Station/channel selection, DATA, FETCH, END, INFO, BYE
• TIME command for time-windowed data requests (v3)
• Sequence tracking and resume from last sequence
• futures::Stream impl via frame_stream() / into_stream()
• Auto-reconnect with exponential backoff and per-station sequence resume
• Built-in deduplication — downstream never sees duplicate frames after reconnect
• miniSEED decode via miniseed-rs integration
• tracing integration for structured logging
• Configurable connect and read timeouts
• Clean EOF handling (next_frame() returns None)

Roadmap

• seedlink-rs-server — async SeedLink server for data distribution
