Tapper v0.3.1 Tapper.TraceId View Source

Generate, parse or format a top-level trace id.

The TraceId comprises the 128-bit Zipkin id, with a second component which is generated using a per-VM unique number sequence, to disambiguate parallel requests to the same server, so each request gets it’s own trace server, which prevents lifecycle confusion.
