Enum ContactValue 

pub enum ContactValue {
    Wildcard,
    Address(Address),
}

A Contact value, which may be the wildcard *.

RFC 3261 §10.2.2: Contact: * with Expires: 0 deregisters everything. It is the one place in the grammar where a header that otherwise holds addresses holds a single asterisk instead, and a parser that expects an address there will reject a legal deregistration.

Variants

Wildcard

* — every registration.

Address(Address)

An ordinary address.
