unroll_range

unroll_range is a Rust macro designed to facilitate the repetition of a block of code for each number within a specified range. This macro is particularly useful for tasks that require repetitive operations over a set of values, like iterations for testing, data processing, or generating output.

Usage

To use unroll_range, include it in your Rust project. Call the macro with a range (inclusive or exclusive) and a closure that performs the operations you wish to repeat.

Parameters

• $range: A Rust range expression (either inclusive or exclusive) over which the block will be repeated.
• $block: A closure that takes a single parameter i and contains the code to execute for each iteration.

Example

Here's how you can use unroll_range with an inclusive range:

unroll_range!(1..=3, |i| {
    println!("Number: {}", i);
});

Comparison

crunchy

crunchy works fine, but adds a lot of boilerplate code, unnecessary if conditions.

repeated

repeated doesn't scope the block, so constants can't be used. It's also using procmacro, which seems to be a bit slower than a macro_rules macro.
