Instance Method Details

#call(severity, time, progname, data) ⇒ String

Override the call method to support hash input/output, and wrap plain strings in a Hash under a msg key. The data is then passed to our custom log formatter that transforms it into a JSON string before logging.

IMPORTANT: This only applies when LogStruct is enabled. When disabled, we preserve the original Rails logging behavior to avoid wrapping messages in hashes (which would break default Rails log formatting).

Parameters:

  • severity (String, Symbol)
  • time (Time)
  • progname (T.untyped)
  • data (T.untyped)

Returns:

  • (String)
