Module Trace_core.LevelSource

Tracing levels.

This is similar to log levels in, say, Logs. In a thoroughly instrumented program, there will be a lot of spans, and enabling them all in production might slow down the application or overwhelm the tracing system; yet they might be useful in debug situations.
