Tracer implementation to create and manage spans

Trait Implementations

impl Tracer for Tracer

type Span = Span

This implementation of api::Tracer produces sdk::Span instances.

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 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: u64)

Mark a given Span as inactive.

impl Clone for Tracer

fn clone(&self) -> Tracer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tracer

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

Formats the value using the given formatter.
