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.UUID parses hyphenated UUID strings, hex UUID strings, and scans into 16-byte arrays
  2. pgtype.UUID marshals to and unmarshals from JSON representations
  3. pgtype.UUID formats valid UUIDs as strings and null UUIDs as driver.Value nil
  4. pgtype.UUID returns an error for invalid UUID strings and unsupported types
  5. pgtype.Timestamp scans time.Time and ISO8601 strings into Timestamp with valid flag
  6. pgtype.Timestamp handles infinity and -infinity values using InfinityModifier
  7. pgtype.Timestamp formats valid timestamps as time.Time and null timestamps as driver.Value nil
  8. pgtype.Timestamptz scans timezone-aware strings and converts to driver.Value time.Time
