Struct EventStream 

Source 
pub struct EventStream { /* private fields */ }
Expand description

A live event stream: a delivery adapter over committed history, not the history itself.

It does not reconnect on its own. When it ends or fails, open a new one from EventStream::last_event_id and nothing committed in between is skipped. For a complete, bounded read of history use the application’s event replay instead.

Implementations§

Source§

impl EventStream

Source

pub fn last_event_id(&self) -> Option<&str>

The cursor of the last event delivered (or the one this stream resumed from).

Source

pub async fn next(&mut self) -> Option<Result<ServerEvent>>

The next event; None when the server closed the stream.

An authority.error event from the server ends the stream with Error::Stream.
