Package wire is used to serialize a trace.

NewContextWithSpan returns a new context with the given Span added.

NewContextWithTrace returns a new context with the given Trace added.

NewTrace starts a new trace and returns a root span identified by the provided name.

NewTraceFromSpan starts a new trace and returns the associated span, which is a child of the parent span context.

SpanFromContext returns the Span associated with ctx or nil if no Span has been assigned.

Walk traverses the graph in a depth-first order, calling v.Visit for each node until completion or v.Visit returns nil.

RawSpan represents the data associated with a span.

The Span type denotes a specific operation for a Trace.

A SpanContext represents the minimal information to identify a span in a trace.

The Trace type functions as a container for capturing Spans used to trace the execution of a request.

A TreeNode represents a single node in the graph.

A Visitor's Visit method is invoked for each node encountered by Walk.

The StartTime start span option specifies the start time of the new span rather than using now.
