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.RowToAddrOfStructByPos maps row columns to struct fields positionally in declaration order and returns a pointer to the struct
  2. pgx.RowToAddrOfStructByPos ignores unexported struct fields when mapping column positions
  3. pgx.RowToAddrOfStructByPos handles nullable pointer fields and assigns nil when column value is null
  4. pgx.RowToAddrOfStructByPos returns an error when column count does not match exported struct field count
  5. pgx.CollectRows with RowToAddrOfStructByPos collects multiple rows into struct pointer slices and closes rows upon completion
  6. pgx.CollectOneRow and pgx.CollectExactlyOneRow work with RowToAddrOfStructByPos and return ErrNoRows and ErrTooManyRows as expected
  7. sample helpers CollectAddrOfStructsByPos, CollectOneAddrOfStructByPos, and CollectExactlyOneAddrOfStructByPos provide typed struct pointer collection
