Struct domain::base::opt::expire::Expire

source ·
pub struct Expire(/* private fields */);
Expand description

Option data for the Expire EDNS option.

The option’s data consists of an optional u32. The value is omitted if the option is added to a query to request it being included by the server in an answer. In this answer the value should be present and indicates the expire time of the zone on the server.

See RFC 7314 for details.
