pub struct TraceContext { /* fields omitted */ }
A TraceContext
represents a distributed trace request.
It consists of a trace ID, the ID of the parent span, the ID of the
context's span, and flags dealing with the sampling of the span.
The trace context is sent to remote services on requests. For example,
it is included in a standard set of headers in HTTP requests.
Returns a builder used to construct a TraceContext
.
Returns the ID of the trace associated with this context.
Returns the ID of the parent of the span associated with this context.
Returns the ID of the span associated with this context.
Returns the sampling flags associated with this context.
Determines if sampling has been requested for this context.
A value of None
indicates that the service working in the context is
responsible for determining if it should be sampled.
Determines if this context is in debug mode.
Debug contexts should always be sampled, regardless of the value of
sampled()
