auto_gauge() is the protocol generic for computing effect-size
quantities from result objects produced by fn in baseline() and
variant(). It is called automatically by gauge() when the result
stored in cld_exec@data is a class_stat_infer subclass.
Details
Register a method on your output class to participate:
S7::method(auto_gauge, my_test_result) = function(x, ...) {
tibble::tibble(metric = "cohens_d", value = ...)
}A variant whose fn returns the same result class as baseline
inherits auto_gauge() for free via S7's parent chain.
