A span represents a single operation within a trace. Spans can be nested to form a trace tree. Often, a trace contains a root span that describes the end-to-end latency, and one or more subspans for its sub-operations.

A trace can also contain multiple root spans, or none at all. Spans do not need to be contiguous. There might be gaps or overlaps between spans in a trace.

Required. The resource name of the span in the following format:

• projects/\[PROJECT_ID\]/traces/\[TRACE_ID\]/spans/\[SPAN_ID\]

\[TRACE_ID\] is a unique identifier for a trace within a project; it is a 32-character hexadecimal encoding of a 16-byte array. It should not be zero.

\[SPAN_ID\] is a unique identifier for a span within a trace; it is a 16-character hexadecimal encoding of an 8-byte array. It should not be zero. .

The \[SPAN_ID\] of this span’s parent span. If this is a root span, then this field must be empty.

display_name: Option<TruncatableString>

See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Required. A description of the span’s operation (up to 128 bytes). Cloud Trace displays the description in the Cloud console. For example, the display name can be a qualified method name or a file name and a line number where the operation is called. A best practice is to use the same display name within an application and at the same call point. This makes it easier to correlate spans in different traces.

Required. The start time of the span. On the client side, this is the time kept by the local machine where the span execution starts. On the server side, this is the time when the server’s application handler starts running.
