Row order of minimal grid returned by min_grid()

[hfrick]

In the example below I would have expected min_grid() to return rows arranged by the non-submodel parameter min_n, instead it seems to be doing: first rows with something in .submodels, then the rest. Not sure it's worth looking into this but wanted to make a note since it's different from the behavior of tidyr::nest().

library(tune)

mod_tune <-
    parsnip::boost_tree(
        trees = tune(),
        min_n = tune(),
        mode = "regression"
    )
model_grid <- list(
  tibble::tibble(trees = 1:2, min_n = 1L),
  tibble::tibble(trees = 2L, min_n = 2L),
  tibble::tibble(trees = 2:3, min_n = 3L)
) |>
  purrr::list_rbind()

min_grid(mod_tune, model_grid)
#> # A tibble: 3 × 3
#>   trees min_n .submodels      
#>   <int> <int> <list>          
#> 1     2     1 <named list [1]>
#> 2     3     3 <named list [1]>
#> 3     2     2 <list [0]>
