Struct vector::trace::TraceSubscription

source · 
pub struct TraceSubscription { /* private fields */ }
Expand description

A subscription to the log events flowing in via tracing, in the Vector native format.

Used to capture tracing events from internal log telemetry, via tracing, and convert them to native Vector events, specifically LogEvent, such that they can be shuttled around and treated as normal events. Currently only powers the internal_logs source, but could be used for other purposes if need be.

Implementations§

source§

impl TraceSubscription

source

pub fn subscribe() -> TraceSubscription

Registers a subscription to the internal log event stream.

source

pub async fn buffered_events(&mut self) -> Option<Vec<LogEvent>>

Gets any early buffered log events.

If this subscription was registered after early buffering was turned off, None will be returned immediately. Otherwise, waits for early buffering to be stopped and returns Some(events) where events contains all events seen from the moment tracing was initialized to the moment early buffering was stopped.

source

pub fn into_stream(self) -> impl Stream<Item = LogEvent> + Unpin

Converts this subscription into a raw stream of log events.
