Interface LDTracer

An OpenTelemetry Tracer enriched with withSpan for React Native, where the active context is tracked only synchronously.

Returned by Observe.getTracer. Implements the full standard Tracer API (startSpan, startActiveSpan) plus the async-safe LDTracer.withSpan helper.

interface LDTracer {
    withSpan<T>(
        spanName: string,
        fn: (scope: SpanScope) => T,
        options?: WithSpanOptions,
    ): T;
}

withSpan<T>(
    spanName: string,
    fn: (scope: SpanScope) => T,
    options?: WithSpanOptions,
): T
Start a span, run fn within it, and end the span automatically.

Same behavior as Observe.withSpan: the callback receives a SpanScope whose SpanScope.child method parents spans correctly across awaits in React Native.
