eventsource-client

Client for the Server-Sent Events protocol (aka EventSource).

Requirements

Requires tokio.

Usage

Example that just prints the type of each event received:

use eventsource_client as es;

let mut client = es::ClientBuilder::for_url("https://example.com/stream")?
    .header("Authorization", "Basic username:password")?
    .build();

client
    .stream()
    .map_ok(|event| println!("got event: {:?}", event))
    .map_err(|err| eprintln!("error streaming events: {:?}", err));

(Some boilerplate omitted for clarity; see examples directory for complete, working code.)

Features

• tokio-based streaming client.
• Supports setting custom headers on the HTTP request (e.g. for endpoints requiring authorization).
• Retry for failed connections.
• Reconnection if connection is interrupted, with exponential backoff.

Stability

Early stage release for feedback purposes. May contain bugs or performance issues. API subject to change.
