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. pgx.CopyFromSlice creates a CopyFromSource from slice length and generator function
  2. CopyFromSource.Values returns transformed row values for each index
  3. CopyFromSource.Next returns false when all items have been consumed
  4. CopyFromSource.Values returns generator error and records it in CopyFromSource.Err
  5. pgx.CopyFromSlice handles empty slice with immediate false on Next
