Expand description
Represents a tracing span.
Fields§
§span_id: SpanId
The ID of the span
trace_id: TraceId
Determines which trace the span belongs to.
parent_span_id: Option<SpanId>
Determines the parent of this span, if any.
same_process_as_parent: Option<bool>
Determines whether this span is generated in the same process as its parent, if any.
op: Option<String>
Short code identifying the type of operation the span is measuring.
description: Option<String>
Longer description of the span’s operation, which uniquely identifies the span but is consistent across instances of the span.
timestamp: Option<SystemTime>
The timestamp at the measuring of the span finished.
start_timestamp: SystemTime
The timestamp at the measuring of the span started.
status: Option<SpanStatus>
Describes the status of the span (e.g. ok
, cancelled
, etc.)
Optional tags to be attached to the span.
data: BTreeMap<String, Value>
Optional extra information to be sent with the span.
