Enum DomainRule 

pub enum DomainRule {
    Any,
    Exact(String),
    Wildcard(String),
    Regex(Regex),
}

Variants

Any

Exact(String)

Wildcard(String)

Matches when hostname ends with s[1..] (the wildcard pattern with the leading * stripped) and the remaining leftmost prefix is non-empty and contains no .. Comparison is byte-exact and no IDN/punycode normalisation is performed here: the pattern was already lowercased by DomainRule::from_str’s idna::domain_to_ascii, and the hostname it is handed has been through normalize_hostname in Router::lookup, so both sides are ASCII-lowercase by the time they meet. Stored with the leading *.

Regex(Regex)

Anchored full-host regex built by convert_regex_domain_rule. Unlike the other variants its source is NOT lowercased — it is compiled case-insensitively instead, so an uppercase literal still matches the normalised key. See DomainRule::from_str for why that folding is Unicode-aware while the hostnames it is ever handed are ASCII.
