Struct TraceSpan 

Source 
pub struct TraceSpan {
    tx: UnboundedSender<RecordMsg>,
    id: RecordId,
    storage_type: StorageType,
}
Expand description

TraceSpan traces hummock operations. It marks the beginning of an operation and the end when the span is dropped. So, please make sure the span live long enough. Underscore binding like let _ = span will drop the span immediately.
