Struct OptBuilder

pub struct OptBuilder<'a> { /* private fields */ }

A builder for the OPT record of a query.

A mutable reference to this type will be passed to the closure given to QueryBuilder::add_opt. It allows manipulation of the record’s header via the header_mut method and adding of options via push.

Limitations

Note that currently this type is not compatible with the various option types‘ push functions. This will be addressed soon by redesigning that mechanism.
