overf

Define the overflow behavior of mathematical operations within blocks of code. This library provides the macros checked!, overflowing!, saturating!, propagating! and default!, enabling you to easily manage overflow in nested contexts.

Features

• Customizable Overflow Behavior: Choose between checked, overflowing, and saturating operations for any block of code.
• Nested Blocks: Define different overflow behaviors in nested blocks for more granular control.
• Reset Behavior: Use the default! macro to reset the overflow behavior back to the default.

Installation

Add the following to your Cargo.toml:

[dependencies]
overf = "0.1"

Usage

use overf::{checked, overflowing, saturating, default};

fn main() {
    checked! {
        let result = 1usize + 1usize;
        let sum = default! { 2usize + 2usize }; // Use default behavior
        let difference = 5usize - 3usize;

        // Nested blocks
        saturating! {
            let total = 100u8 - 200u8;
        }
    }

    overflowing! {
        let result = 1usize + usize::MAX;
    }
}
