Reading and writing event logs

readEventLogFromFile :: FilePath -> IO (Either String EventLog) Source #

Read an entire eventlog file. It returns an error message if it encouters an error while decoding.

Note that it doesn't fail if it consumes all input in the middle of decoding of an event.

writeEventLogToFile :: FilePath -> EventLog -> IO () Source #

Writes the EventLog to file. The log is expected to NOT have EventBlock markers/events - the parsers no longer emit them and they are handled behind the scenes.

serialiseEventLog :: EventLog -> ByteString Source #

Serialises an EventLog back to a ByteString, usually for writing it back to a file.

Utilities
