Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

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
