Struct MetricsObserver 

pub struct MetricsObserver { /* private fields */ }

Observer that maintains a GraphMetrics under a Mutex.

Implementations

impl MetricsObserver

pub fn new() -> Self

Empty observer.

pub fn snapshot(&self) -> GraphMetrics

Snapshot the current metrics.

Trait Implementations

impl Default for MetricsObserver

fn default() -> Self

Returns the “default value” for a type.

impl Observer for MetricsObserver

fn on_event(&self, event: &Event)

Called for every event emitted during execution. Implementations should be cheap and non-blocking — a slow observer slows execution.
