Trait opentelemetry::global::ObjectSafeTracer

pub trait ObjectSafeTracer {
    // Required method
    fn build_with_context_boxed(
        &self,
        builder: SpanBuilder,
        parent_cx: &Context,
    ) -> Box<dyn ObjectSafeSpan + Send + Sync>;
}

Available on crate feature trace only.

Allows a specific Tracer to be used generically by BoxedTracer instances by mirroring the interface and boxing the return types.

Required Methods

fn build_with_context_boxed( &self, builder: SpanBuilder, parent_cx: &Context, ) -> Box<dyn ObjectSafeSpan + Send + Sync>

Returns a trait object so the underlying implementation can be swapped out at runtime.
