 This is a required option because some of the below settings are considered "unstable" by rustfmt.
 
+### `combine_control_expr = false`
+
+Separates control expression from their function calls:

+### `condense_wildcard_suffixes = true`
+
+Replaces consecutive underscore variables with a single `..` within tuple patterns:

+```rs
+let (lorem, ipsum, _, _) = (1, 2, 3, 4);
+// becomes
+let (lorem, ipsum, ..) = (1, 2, 3, 4);

+
+### `fn_single_line = true`
+
+Puts single-expression functions on a single line:

+```rs
+fn lorem() -> usize { 42 }

+
+### `format_code_in_doc_comments = true`
+
+Formats code snippets in doc comments.
+
+### `format_macro_matchers = true`
+
+Formats metavariables in macro declarations:

+### `reorder_impl_items = true`
+
+Reorders impl items. `type` and `const` are grouped together, then macros and functions:
