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 iterates through rows and collects primitive types using pgx.RowTo
  2. pgx.CollectRows maps column fields into struct using pgx.RowToStructByName
  3. pgx.CollectRows maps pointer to struct using pgx.RowToAddrOfStructByName
  4. pgx.CollectRows handles subset columns with pgx.RowToStructByNameLax
  5. pgx.CollectRows scans column key-value pairs into map using pgx.RowToMap
  6. pgx.CollectOneRow extracts a single row and returns pgx.ErrNoRows when result is empty
  7. pgx.CollectExactlyOneRow returns pgx.ErrTooManyRows when query yields more than one row
  8. pgx.CollectRows closes rows automatically on completion and returns empty slice for zero rows
