1 2	log_redis(con, key, ..., .warning = TRUE, .error = TRUE, .message = TRUE, .formatter = format_log_entry_json, subscriptions = NULL)

`con`	A redis connection object, created by `RedisAPI::hiredis`.
`key`	Key to log to. If this exists it must be a list (this is enforced in this function but must remain true while logging is active).
`...`	list of quoted or unquoted events to log. In none are provided all log events will be captured.
`.warning`	logical: capture regular warnings (`simpleWarning`)?
`.error`	logical: capture regular errors (`simpleError`)?
`.message`	logical: capture regular messages (`simpleMessage`)?
`.formatter`	function: the formatting function used to convert a log event to its character representation for the log file. Note that the default formatter here is to JSON, not to text.
`subscriptions`	character vector: optional list of subscriptions to use (in place of specifying with `...`).
