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. pgx.CollectRows transforms query rows into a slice using a row mapping function and closes rows
  2. pgx.CollectOneRow returns the first row mapped by a row mapping function
  3. pgx.CollectOneRow returns pgx.ErrNoRows when the row set is empty
  4. pgx.CollectExactlyOneRow returns a mapped row when exactly one row is available
  5. pgx.CollectExactlyOneRow returns pgx.ErrTooManyRows when more than one row is present
  6. pgx.RowToStructByName maps column values to struct fields by db struct tag
  7. pgx.RowToMap collects column names and values into a map of string to any
