byte-repr

byte-repr is a lightweight Rust crate for inspecting the memory representation of numeric values. It helps visualize the binary, little-endian, and big-endian byte representations, including their hex format with zero padding.

Useful for:

Learning and teaching byte order (endianness)
Debugging binary data
Understanding how integers are stored in memory

✨ Features

Print values in:
- Binary format
- Little-endian byte array
- Big-endian byte array
- Hexadecimal representation with zero padding
Color-coded output for clarity
Macro-based extensibility for numeric types

🚀 Usage

Add this to your Cargo.toml:

[dependencies]
byte-repr = "0.1.0" # update after publishing

Then use in your code:

use byte_repr::represent;

fn main() {
    let x = 42u16;
    represent(&x);
}

Example Output:
