One has to follow your link to Wikipedia, to find out why you are implementing only half of wildcard syntax. Only that article admits to limiting itself to Windows' limited features.

Rust also runs on Linux and other systems implementing \\, \*, \?, [char-classes] and {multi,branches} (though Bash treats those a little bit apart.) You should be clearer about this!

As for your benchmark, you could also compare to regex-lite. And either give Unicode examples, or state that you skip it for performance reasons.
