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. pgtype.Array scans 1D text array literals preserving elements and dimensions
  2. pgtype.Array.SetDimensions configures multidimensional bounds and resizes internal elements
  3. pgtype.FlatArray scans 1D array literals into flat Go slices implementing ArrayGetter and ArraySetter
  4. pgtype.Array and pgtype.FlatArray Index, IndexType, and ScanIndex access elements and element types
  5. pgtype.Map encodes and decodes multidimensional pgtype.Array across binary wire format
  6. pgtype.Array scans nil source into invalid array representing SQL NULL
  7. pgtype.Array returns an error when scanning malformed array literals or invalid element formats
  8. pgtype.Map encodes pgtype.Array into PostgreSQL formatted text array literal
  9. Sample helper functions parse string arrays, flat int64 arrays, construct 2D arrays, and encode binary formats
