Struct opentelemetry::global::BoxedTracer

pub struct BoxedTracer(_);

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

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 invalid(&self) -> Self::Span

Returns a span with an inactive SpanContext. Used by functions that need to return a default span like get_active_span if no span is present.

fn start(&self, name: &str, parent_span: Option<SpanContext>) -> Self::Span

Starts a new Span.

Each span has zero or one parent spans and zero or more child spans, which represent causally related operations. A tree of related spans comprises a trace. A span is said to be a root span if it does not have a parent. Each trace includes a single root span, which is the shared ancestor of all other spans in the trace.

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

Creates a span builder

An ergonomic way for attributes to be configured before the Span is started.

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

Create a span from a SpanBuilder

fn get_active_span(&self) -> Self::Span

Returns the current active span.

When getting the current Span, the Tracer will return a placeholder Span with an invalid SpanContext if there is no currently active Span.

fn mark_span_as_active(&self, span: &Self::Span)

Mark a given Span as active.

fn mark_span_as_inactive(&self, span_id: SpanId)

Mark a given Span as inactive.

fn clone_span(&self, span: &Self::Span) -> Self::Span

Clone span
