Description
In some past version (I don't remember which one), rust-analyzer started adding parentheses to functions in autocomplete suggestions. In the example below, parentheses are appended to function names:
- functions without arguments receive
(); - those with arguments receive
(...):

My suggestion is making these parentheses optional, so their rendering can be enabled or disabled by the user.
