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.

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 start_with_context<T>(&self, name: T, parent_cx: &Context) -> Self::Spanwhere T: Into<Cow<'static, str>>,

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<T>(&self, name: T) -> SpanBuilderwhere T: Into<Cow<'static, str>>,

Creates a span builder

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

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

Starts a new Span.

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

Create a span from a SpanBuilder

fn in_span<T, F>(&self, name: &'static str, f: F) -> Twhere F: FnOnce(Context) -> T, Self::Span: Send + Sync + 'static,

Start a new span and execute the given closure with reference to the span’s context.

fn with_span<T, F>(&self, span: Self::Span, f: F) -> Twhere F: FnOnce(Context) -> T, Self::Span: Send + Sync + 'static,

Start a new span and execute the given closure with reference to the span’s context.
