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.Circle.Scan parses PostgreSQL formatted circle string <(x,y),r> into center coordinates and radius
  2. pgtype.Circle.Scan handles nil input by setting Valid to false to represent SQL NULL
  3. pgtype.Circle.Value returns formatted driver string for valid circle and nil for SQL NULL
  4. pgtype.Circle.CircleValue returns underlying Circle struct and nil error for valid instance
  5. pgtype.Circle.ScanCircle copies center coordinates, radius, and validity from source to destination
  6. pgtype.Circle.Scan returns an error for malformed circle string literals
  7. pgtype.Map encodes and decodes pgtype.Circle across PostgreSQL text and binary wire formats
