TelemetryDriver

rustfoundry::telemetry

Struct TelemetryDriver 

Source 
pub struct TelemetryDriver { /* private fields */ }
Available on crate features logging or metrics or telemetry or tracing only.
Expand description

A future that drives async telemetry functionality and that is returned by crate::telemetry::init.

You would usually need to pass it to tokio::spawn once all the security syscall-related configuration steps are completed.

Implementations§

Source§

impl TelemetryDriver

Source

pub fn server_addr(&self) -> Option<SocketAddr>

Available on crate feature telemetry-server only.

Address of the telemetry server.

Returns None if the server wasn’t spawned.

Source

pub fn with_graceful_shutdown( &mut self, signal: impl Future<Output = ()> + Send + Sync + 'static, )

Instructs the telemetry driver and server to perform an orderly shutdown when the given future signal completes.

If telemetry is disabled, the given signal is still awaited before driver termination.
