Optional isOnly true if the SpanContext was propagated from a remote parent.
The ID of the Span. It is globally unique with practically sufficient probability by being made as 8 randomly generated bytes, encoded as a 16 lowercase hex characters corresponding to 64 bits.
Trace flags to propagate.
It is represented as 1 byte (bitmap). Bit to represent whether trace is sampled or not. When set, the least significant bit documents that the caller may have recorded trace data. A caller who does not record trace data out-of-band leaves this flag unset.
see otel.TraceFlags for valid flag values.
The ID of the trace that this span belongs to. It is worldwide unique with practically sufficient probability by being made as 16 randomly generated bytes, encoded as a 32 lowercase hex characters corresponding to 128 bits.
Optional traceTracing-system-specific info to propagate.
The tracestate field value is a list as defined below. The list is a
series of list-members separated by commas ,, and a list-member is a
key/value pair separated by an equals sign =. Spaces and horizontal tabs
surrounding list-members are ignored. There can be a maximum of 32
list-members in a list.

A SpanContext represents the portion of a Span which must be serialized and propagated along side of a otel.Baggage.
