Implementations

impl Question

pub fn new<S: Into<String>>(md: S) -> Self

Create a new question with some text.

pub fn add_answer<K: Display, S: Into<String>>(&mut self, key: K, md: S)

add a proposed answer, with a key

The user will have to type the result of calling to_string() on the key (numbers, chars, or strings are naturally good options for keys)

pub fn set_default<K: Display>(&mut self, default_answer: K)

set the value which will be returned if the user only hits enter.

It does not have to be one of the answers’ key, except when you use the ask! macro.

pub fn has_exotic_default(&self) -> bool

has a default been defined which isn’t among the list of answers?

pub fn ask(&self, skin: &MadSkin) -> Result<String>

Does the asking and returns the inputted string, unless the user just typed enter and there was a default value.

If the user types something not recognized, he’s asking to try again.
