Crate iffy 

This crate defines a macro to imitate the ternary operator found in C-like languages such as C, C++, Java, etc. The macro can be used to make more compact conditional expressions in Rust code.

For example, this code in plain rust:

let a = 20;
let b = 30;

// This is the part we will be able to simplify
let min = if a < b {
    a
} else {
    b
};

// Check the result
assert_eq!(min, a);

… Can be shortened to the following, with this crate:

let a = 20;
let b = 30;

// Shortened from the previous example
let min = iffy::i!(a < b ? a : b);

// Check the result
assert_eq!(min, a);
