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.RowToStructByPos maps positional row columns to public struct fields in sequential order
  2. pgx.RowToAddrOfStructByPos scans and returns pointers to allocated structs
  3. pgx.RowToStructByPos ignores struct fields tagged with db:"-"
  4. pgx.RowToStructByPos ignores unexported struct fields when matching column positions
  5. pgx.AppendRows appends scanned rows into an existing pre-allocated slice
  6. pgx.AppendRows automatically closes rows upon completion
  7. pgx.RowToStructByPos returns an error when column count does not match exported struct field count
  8. pgx.AppendRows returns an error when row iteration encounters an error
