# [return] A named logical vector, where each key is a metric name and each value is a boolean.
# TRUE if higher values of the metric are desirable, FALSE if lower values are desirable.
# Note that only the 'main' metrics are stored here, not aliases, since only the 'main' metrics
# are returned from the C++ side. For example, if you use `metric = "mse"` in your code,
# the metric name `"l2"` will be returned.
