Function fif::files::mime_extension_lookup

pub fn mime_extension_lookup(essence: String) -> Option<Vec<String>>

Returns a list of known extensions for this MIME type, if any. This function uses the Mime’s “essence” rather than the Mime itself - mime_guess::get_mime_extensions ignores the type suffix, treating “image/svg+xml” as “image/svg”, and thus fails to find any extensions. Passing the essence_str (which includes the suffix) fixes this.
