Function actix_web_lab::sse::channel

pub fn channel(buffer: usize) -> (Sender, Sse<ChannelStream>)

Create server-sent events (SSE) channel pair.

The buffer argument controls how many unsent messages can be stored without waiting.

The first item in the tuple is the sender half. Much like a regular channel, it can be cloned, sent to another thread/task, and send event messages to the response stream. It provides several methods that represent the event-stream format.

The second item is the responder and can, therefore, be used as a handler return type directly. The stream will be closed after all senders are dropped.

See module docs for usage example.
