This function provides an easy way to set the basic log
layout of the pipeline logging. For a fine-grained control of the logger,
which you can retrieve via lgr::get_logger("pipeflow"), see e.g. the
logger_config function from the lgr package.
Usage
set_log_layout(layout = c("text", "json"))Examples
p <- Pipeline$new("pipe", data = 1:2)
p$add("add1", \(data = ~data, x = 1) x + data)
p$run()
