As a user of the library, comparing mime types as strings isn't as optimal as matching enum variants

[KSXGitHub]

To get specific file types, I have to either call Type::mime_type() or Type::extension(). They both return &'static str which would require string comparison to work with.

Since returning a custom enum is little different from returning string literals/constants, I suggest providing an API to return different mime type enum. There are currently 10 MatcherType, so it makes sense to define 10 new enum types plus 1 to contain all of them.

I don't know if the Rust compiler can optimize comparison of &'static str into simple number comparison, but I'd rather not rely on optimizer magic.

Your code is simple enough. So if you find this feature worth adding, I'm willing to create a PR. The matcher_map enum would changes its structure.
