Struct ProfileSelectorUsernameParser 

pub struct ProfileSelectorUsernameParser { /* private fields */ }

Available on crate features std and ua only.

Parses ua_<word> username labels into a UserAgent that selects the profile ProfileEmulateLayer emulates.

Each label names a browser, platform or device, as the User-Agent classifier reads them: john-ua_chrome-ua_macos selects Chrome on macOS and john-ua_mobile any mobile profile. Without such labels no UserAgent is inserted and selection stays unrestricted. A word that names no class, or one that contradicts an earlier label, aborts parsing.

Key and value share one label, so it combines with other parsers as a tuple, such as the proxy filter parser of rama-proxy: john-country-ua-ua_firefox selects a Ukrainian proxy and a Firefox profile.
