Code
  (expect_error(cur_column()))
Output
  <error/rlang_error>
  Error in `cur_column()`:
  ! Must only be used inside `across()`.
Code
  (expect_error(cur_group()))
Output
  <error/rlang_error>
  Error in `cur_group()`:
  ! Must only be used inside data-masking verbs like `mutate()`, `filter()`, and `group_by()`.
Code
  (expect_error(cur_group_id()))
Output
  <error/rlang_error>
  Error in `cur_group_id()`:
  ! Must only be used inside data-masking verbs like `mutate()`, `filter()`, and `group_by()`.
Code
  (expect_error(cur_group_rows()))
Output
  <error/rlang_error>
  Error in `cur_group_rows()`:

group labels are correctly formatted

Code
  group_labels_details(c(a = 1))
Output
  [1] "`a = 1`"
Code
  group_labels_details(c(a = 1, b = 2))
Output
  [1] "`a = 1`, `b = 2`"
