This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

  1. limit := rate.Every(100 * time.Millisecond)
  2. limit == rate.Limit(10)
  3. rate.Every(0) == rate.Inf
  4. limiter := rate.NewLimiter(rate.Limit(5), 2)
  5. limiter.Limit() == rate.Limit(5)
  6. limiter.SetLimit(rate.Limit(20))
  7. limiter.Limit() == rate.Limit(20)
  8. unlimited := rate.NewLimiter(rate.Inf, 0)
  9. unlimited.Limit() == rate.Inf
  10. unlimited.Allow() == true
