[−][src]Trait opentelemetry::trace::FutureExt

pub trait FutureExt: Sized {
    fn with_context(self, otel_cx: OpenTelemetryContext) -> WithContext<Self> { ... }
    fn with_current_context(self) -> WithContext<Self> { ... }
}

Extension trait allowing futures, streams, and sinks to be traced with a span.
