safe_format

safe_format is a procedural macro for Rust that allows you to safely format strings with named parameters. It works similarly to the built-in format! macro but allows for named parameters, and it safely ignores any extra parameters that are not used in the format string.

Features

• Named parameters for string formatting.
• Ignores extra parameters that are not used in the format string.
• Simple and intuitive API.

Usage

use safe_format::safe_format;

fn main() {
    let name = "Allen";
    let age = 19;
    let pattern = "Greeting from {name}";
    let greeting = safe_format!(pattern, name = name, age = age);
    println!("{}", greeting);  // Output: Greeting from Allen
}
