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.)

tags: BTreeMap<String, String>

Optional tags to be attached to the span.

data: BTreeMap<String, Value>

Optional extra information to be sent with the span.
