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:

🔧 Supported Types

Currently supports:

• i8
• u16
• u32

More can be added using the impl_byterep! macro.
