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.Multirange scans PostgreSQL text formatted multirange literals into slice of pgtype.Range elements with proper bounds and bound types
  2. pgtype.Map encodes pgtype.Multirange into PostgreSQL text formatted multirange literal representation
  3. pgtype.Map encodes and decodes pgtype.Multirange across PostgreSQL binary wire format preserving range values and bounds
  4. pgtype.Map.Scan parses empty multirange {} into an empty slice with length 0
  5. pgtype.Map.Scan scans nil data into a nil multirange representing SQL NULL
  6. pgtype.Map.Scan returns an error when scanning malformed multirange string literals
