pub trait ComposeQuestion {
// Required method
fn compose_question<Target: Composer + ?Sized>(
&self,
target: &mut Target,
) -> Result<(), Target::AppendError>;
}Expand description
A helper trait allowing construction of questions on the fly.
The trait’s primary user is the QuestionBuilder type of the message
builder system. It’s push method accepts anything that implements
this trait.
Implementations are provided for Question values and references. In
addition, a tuple of a domain name, record type and class can be used as
this trait, saving the detour of constructing a question first. Since
the class is pretty much always Class::IN, a tuple of just a domain
name and record type works as well by assuming that class.
Required Methods§
fn compose_question<Target: Composer + ?Sized>( &self, target: &mut Target, ) -> Result<(), Target::AppendError>
Object Safety§
This trait is not object safe.
