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.NewMap initializes TypeMap with standard PostgreSQL types registered
  2. pgtype.Map.Encode converts Go types to text format byte slice
  3. pgtype.Map.Scan decodes text format byte slice into Go primitive types
  4. pgtype.Map.Scan decodes PostgreSQL boolean text format into Go bool
  5. pgtype.Map.Scan handles SQL NULL by setting pgtype nullable values to invalid
