If it does, then the diff() function return value contains these values. To get these values, you can use [from.startidx, from.endidx - from.startidx + 1, to.startidx, to.endidx - to.startidx + 1] for a diff hunk. I see that the Neovim vim.diff() function returns these values when using the {result_type = 'indices'} option.
