Trait requestty::prompt::Prompt

pub trait Prompt: Debug {
    fn ask(

        backend: &mut dyn Backend,
        events: &mut dyn EventIterator
    ) -> Result<Option<Answer>>;
}

Prompts are a way to write custom Questions.

The prompt is given a message, the previous Answers and a Backend and EventIterator. Using these, it is responsible for doing everything from rendering to user interaction. While no particular look is enforced, it is recommended to keep a similar look to the rest of the in-built questions.

You can use the requestty-ui crate to build the prompts. You can see the implementations of the in-built questions for examples on how to use it.
