function Span::getSpanId

A unique identifier for a span within a trace, assigned when the span is created. The ID is an 8-byte array. An ID with all zeroes OR of length other than 8 bytes is considered invalid (empty string in OTLP/JSON is zero-length and thus is also invalid). This field is required.

Generated from protobuf field <code>bytes span_id = 2;</code>
