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.Scan parses standard 36-character hyphenated UUID strings into 16-byte representation with Valid true
  2. pgtype.UUID.Scan parses 32-character compact hexadecimal UUID strings without hyphens
  3. pgtype.UUID.Scan handles nil input by setting Valid to false to represent SQL NULL
  4. pgtype.UUID.Value returns 36-character hyphenated string for valid UUID and nil for invalid UUID
  5. pgtype.UUID.ScanUUID copies UUID bytes and validity from another UUID instance
  6. pgtype.UUID.UUIDValue extracts the underlying UUID value
  7. pgtype.UUID.Scan returns an error for invalid UUID string formats or invalid lengths
