Struct Select 

pub struct Select { /* private fields */ }

A question that a user answers with one of several options

The options are the texts that the user sees, in the order of display. The answer is the position of one option, and the first option has the position zero.

Prompt::select builds this type from the Display text of its options and sends it to the presenter. A command does not usually build it.

Examples

use clawless_core::prompt::Select;

let question = Select::new("Kind of change", ["Added", "Changed", "Fixed"]);

assert_eq!(question.options().len(), 3);
