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.CollectRows transforms query rows into a slice using a row mapping function and closes rows
  2. pgx.CollectOneRow returns the first row mapped by a row mapping function
  3. pgx.CollectOneRow returns pgx.ErrNoRows when the row set is empty
  4. pgx.CollectExactlyOneRow returns a mapped row when exactly one row is available
  5. pgx.CollectExactlyOneRow returns pgx.ErrTooManyRows when more than one row is present
  6. pgx.RowToStructByName maps column values to struct fields by db struct tag
  7. pgx.RowToMap collects column names and values into a map of string to any
