Trait StringPromptable

pub trait StringPromptable {
    // Required method
    fn prompt(output: &str) -> Self;
}

A trait that defines prompt functionality for obtaining user input as a String.

This trait allows any type that implements StringPromptable to provide a prompt for user input, making it easier to capture data of type String.

Methods

• prompt: Displays a prompt message to the user and returns the input as the type implementing the trait.

Required Methods

fn prompt(output: &str) -> Self

Displays a prompt message to the user and returns the input as the type that implements the trait.

Parameters

• output: The message that will be shown to the user.

Examples

let name: String = String::prompt("What is your name? ");

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
