Struct BinaryQuery

Source 
pub struct BinaryQuery<T>
where
    T: Display,
{
    pub positive_choice: T,
    pub negative_choice: T,
    pub answer: String,
}
Expand description

Represents the answer to a query posted to the user.

Fields§

§positive_choice: T

For a binary query we have exactly to choices. A positive and a negative one. These choices do not need to be ‘yes’ or ‘no’, but can be generic. The only thing we need to be able to do is to communicate them.

§negative_choice: T§answer: String
