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.CopyFromRows transforms a 2D slice into a CopyFromSource interface
  2. pgx.CopyFromSlice transforms a slice via generator function into a CopyFromSource interface
  3. pgx.CopyFromSlice captures and propagates generator function errors during iteration
  4. pgx.RowToStructByPos maps positional query columns directly into struct fields
  5. pgx.RowToAddrOfStructByPos maps positional query columns into an allocated struct pointer
  6. pgx.RowToAddrOfStructByName maps query columns into an allocated struct pointer using db struct field tags
