Delete all files except folder and file?

Question

linux

Gentlemen, can you tell me how to delete all the files in the directory and leave only one folder with all the files, and one file in another folder?
You need to leave the src directory with files
and one public/index.html file.
This does not work.
rm -rf ./!(src|public/index.html)
Thanks
