virtual void UpdateName(nostd::string_view name) noexcept = 0¶

virtual void End(const EndSpanOptions &options = {}) noexcept = 0¶

Mark the end of the Span. Only the timing of the first End call for a given Span will be recorded, and implementations are free to ignore all further calls.

Parameters: options – can be used to manually define span properties like the end timestamp
