CIO - Console I/O for Rust

CIO provides two procedural macros (printf! and input!) that improve console input/output operations in Rust, bringing Python’s convenience to Rust’s safely typed environment.

Features

printf!

An enhanced formatted display macro that allows for better visualization of complex data structures such as multidimensional arrays.

use cio::printf;

let arr = vec![vec![1, 2], vec![3, 4]];
printf!("Array: {arr:a}");

input!

A user input macro with built-in type validation.

use cio::input;

let number: i32 = input!("Enter a number: ");

Macros

input

Procedural macro that facilitates user input and validation.

printf

Procedural macro that implements formatted output similar to C’s printf but with enhanced features for Rust.
