Enum UnsubscribeMethod 

pub enum UnsubscribeMethod {
    OneClick {
        url: Url,
    },
    HttpLink {
        url: Url,
    },
    Mailto {
        address: String,
        subject: Option<String>,
    },
    None,
}

The unsubscribe action a message exposes via its headers.

Returned by parse and parse_with_post. The OneClick variant is only produced when an RFC 8058 List-Unsubscribe-Post header is present and an HTTPS or HTTP URL is available in the main header.

Variants

OneClick

RFC 8058 one-click. The caller should POST to url with body List-Unsubscribe=One-Click and Content-Type: application/x-www-form-urlencoded.

Fields

url: Url

HttpLink

A plain HTTP(S) link the user should open in a browser. May require further interaction (preference page, confirmation click).

Fields

url: Url

Mailto

Send an email to address with optional subject. The body, if any was specified in the mailto: query, is intentionally dropped — see the crate README for the rationale.

Fields

address: String

subject: Option<String>

None

No List-Unsubscribe header was found, or every candidate was unparseable.
