Struct opentelemetry::global::BoxedTracer

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

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

Implementations

impl BoxedTracer

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

Create a BoxedTracer from an object-safe tracer.

Trait Implementations

impl Debug for BoxedTracer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.

fn build_with_context( &self, builder: SpanBuilder, parent_cx: &Context, ) -> Self::Span

Create a span from a SpanBuilder

fn start<T>(&self, name: T) -> Self::Span

where T: Into<Cow<'static, str>>,

Starts a new Span.

fn start_with_context<T>(&self, name: T, parent_cx: &Context) -> Self::Span

where T: Into<Cow<'static, str>>,

Starts a new Span with a given context.

fn span_builder<T>(&self, name: T) -> SpanBuilder

where T: Into<Cow<'static, str>>,

Creates a span builder.

fn build(&self, builder: SpanBuilder) -> Self::Span

Start a Span from a SpanBuilder.

fn in_span<T, F, N>(&self, name: N, f: F) -> T

where F: FnOnce(Context) -> T, N: Into<Cow<'static, str>>, Self::Span: Send + Sync + 'static,

Start a new span and execute the given closure with reference to the context in which the span is active.
