Sample Code

// Set global resource attributes.
if (msServiceProfiler::Tracer::IsEnable()) {
    msServiceProfiler::TraceContext::addResAttribute("service.name", "my-service");
    msServiceProfiler::TraceContext::addResAttribute("service.version", "1.0.0");
}
auto& ctx = msServiceProfiler::TraceContext::GetTraceCtx();
size_t indexHeader = ctx.ExtractAndAttach(traceParentHeader, b3Header);
size_t index = ctx.Attach(TraceId{1, 1}, SpanId{1}, true);  // The span is automatically attached. Generally, you do not need to call this function.
// Create a span.
auto span = msServiceProfiler::Tracer::StartSpanAsActive("MyOperation", "MyModule");
// Set attributes.
span.SetAttribute("key", "value")
    .SetStatus(true, "Operation completed successfully");
span.End();
ctx.Unattach(index);
ctx.Unattach(indexHeader);
