Expand description

The Tracer trait is responsible for creating spans and managing the active span in distributed tracing.

This trait defines methods for starting new spans, starting spans with a parent, and retrieving the namespace of the tracer.

Required Methods§

Source

fn start_span( &self, name: &'static str, kind: SpanKind, attributes: Vec<Attribute>, ) -> Arc<dyn Span>

Starts a new span with the given name and type.

The newly created span will have the “current” span as a parent.

§Arguments
  • name: The name of the span to start.
  • kind: The type of the span to start.
  • attributes: A vector of attributes to associate with the span.
§Returns

An Arc<dyn Span> representing the started span.

Source

fn start_span_with_parent( &self, name: &'static str, kind: SpanKind, attributes: Vec<Attribute>, parent: Arc<dyn Span>, ) -> Arc<dyn Span>

Starts a new child with the given name, type, and parent span.

§Arguments
  • name: The name of the span to start.
  • kind: The type of the span to start.
  • attributes: A vector of attributes to associate with the span.
  • parent: The parent span to use for the new span.
§Returns

An Arc<dyn Span> representing the started span

Note: This method may panic if the parent span cannot be downcasted to the expected type.

Source

fn namespace(&self) -> Option<&'static str>

Returns the namespace the tracer was configured with (if any).

§Returns

An Option<&'static str> representing the namespace of the tracer,
