pub struct BoxedTracer(/* private fields */);
Expand description

Wraps the GlobalTracerProvider’s Tracer so it can be used generically by applications without knowing the underlying type.

Implementations§

source§

impl BoxedTracer

source

pub fn new(tracer: Box<dyn ObjectSafeTracer + Send + Sync>) -> Self

Create a BoxedTracer from an object-safe tracer.

impl Tracer for BoxedTracer

§

type Span = BoxedSpan

Global tracer uses BoxedSpans so that it can be a global singleton, which is not possible if it takes generic type parameters.
