Crate surf_sse 

An implementation of the EventSource API using Surf.

Surf Cargo Features

surf-sse wraps the Surf library. By default, surf-sse uses the default Surf features. If you are using a non-default Surf client implementation or feature set, you can disable surf-sse’s default feature:

surf = { version = "*", features = ["hyper-client"] }
surf-sse = { version = "*", default-features = false }

This way, surf-sse will also use the “hyper-client” feature.

Logging

surf-sse uses the log crate for some rudimentary connection logging. If you need to debug an EventSource connection, enable trace logging for the surf-sse target. For example, with env_logger:

RUST_LOG=surf-sse=trace \
cargo run

Examples

use futures_util::stream::TryStreamExt; // for try_next()
use surf_sse::EventSource;

let mut events = EventSource::new("https://announce.u-wave.net/events".parse().unwrap());

while let Some(message) = events.try_next().await.unwrap() {
    dbg!(message);
}
