input-rust 🦀

A simple Rust crate that mimics Python's input() function with error handling. It prompts the user for input, trims it, and ensures it's not empty before returning the result.

Features

Prompts the user for input with a custom message.
Returns an error if the input is empty.
Provides error handling for input failures.

Installation

Add this to your Cargo.toml file:

[dependencies]
input-rust = "1.0.0"

Usage

You can use the input function to prompt the user for input:

use input_rust::input;

fn main() {
    match input("Please enter some text: ") {
        Ok(value) => println!("You entered: {}", value),
        Err(e) => println!("Error: {}", e),
    }

    let text = input("Please enter some text: ").unwrap(); 
    println!("{}", text);
}

Error Handling

If the user enters an empty string or an error occurs, the input function will return an error with a descriptive message:

If the input is empty, an InvalidInput error is returned.
If there is any other error reading the input, it returns an error of type Other.
