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.Identifier Sanitize formats multi-part identifiers with double quotes and dot separators
  2. pgx.Identifier Sanitize escapes embedded double quotes by doubling them
  3. pgx.CopyFromRows iterates through 2D slice rows and makes row values available via Values
  4. pgx.CopyFromRows handles empty row sets with immediate false from Next and nil Err
  5. pgx.CopyFromSlice invokes index mapping function and returns converted row values
  6. pgx.CopyFromSlice captures and surfaces conversion errors encountered during row mapping
  7. pgx.CopyFromSlice handles zero length input with immediate false from Next and nil Err
  8. pgx.CopyFromFunc consumes generator function until exhaustion and surfaces generator errors
  9. pgx.CopyFromRows, pgx.CopyFromSlice, and pgx.CopyFromFunc implement pgx.CopyFromSource interface
