@@ -60,6 +60,6 @@ Creating a Logger using `logging.Logger` accept configuration [LoggerOption](log
 | EntryByteLimit | `int` | Maximum size in bytes of the single write call to ingest log entries. If EntryByteLimit is smaller than EntryByteThreshold, the latter has no effect. The default is zero, meaning there is no limit. |
 | BufferedByteLimit | `int` | Maximum number of bytes that the Logger will keep in memory before returning ErrOverflow. This option limits the total memory consumption of the Logger (but note that each Logger has its own, separate limit). It is possible to reach BufferedByteLimit even if it is larger than EntryByteThreshold or EntryByteLimit, because calls triggered by the latter two options may be enqueued (and hence occupying memory) while new log entries are being added. |
 | ContextFunc | `func() (ctx context.Context, afterCall func())` | Callback function to be called to obtain `context.Context` during async log ingestion. |
-| SourceLocationPopulation | One of `logging.DoNotPopulateSourceLocation`, `logging.PopulateSourceLocationForDebugEntries` or `logging.AlwaysPopulateSourceLocation` | Controls auto-population of the logging.Entry.SoourceLocation field when ingesting log entries. Allows to disable population of source location info, allowing it only for log entries at Debug severity or enable it for all log entries. Enabling it for all entries may result in degradation in performance. Use `logging_test.BenchmarkSourceLocationPopulation` to test performance with and without the option. The default is set to `logging.DoNotPopulateSourceLocation`. |

 | RedirectAsJSON | `io.Writer` | Converts log entries to Jsonified one line string according to the [structured logging format](https://cloud.google.com/logging/docs/structured-logging#special-payload-fields) and writes it to provided `io.Writer`. Users should use this option with `os.Stdout` and `os.Stderr` to leverage the out-of-process ingestion of logs using logging agents that are deployed in Cloud Logging environments. |
