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.

Contract

  1. multierr.Combine merges multiple errors into a single error preserving all non-nil errors
  2. multierr.Append appends a secondary error onto a primary error
  3. multierr.AppendInto appends an error into a pointer destination and reports whether an error was added
  4. multierr.AppendFunc and multierr.AppendInvoke safely capture deferred error-returning functions and closers
  5. multierr.Errors inspects and extracts the underlying slice of errors from a combined error
