Module bit

Bit Manipulation and Machine Integer Utilities

This module provides utilities for working with individual bits and machine integer types. It defines a Bit enum to represent a single bit (0 or 1) along with convenient conversion implementations between Bit, bool, and various primitive integer types.

In addition, the module introduces the MachineInteger trait which abstracts over integer types, providing associated constants:

• BITS: The size of the integer type in bits.
• SIGNED: A flag indicating whether the type is signed.

The Bit type includes methods for extracting the value of a specific bit from an integer. For example, Bit::of_int returns the bit at a given position for a provided integer, handling both positive and negative values (assuming a two’s complement representation).

Examples

use core_models::abstractions::bit::{Bit, MachineInteger};

// Extract the 3rd bit (0-indexed) from an integer.
let bit = Bit::of_int(42, 2);
println!("The extracted bit is: {:?}", bit);

// Convert Bit to a primitive integer type.
let num: u8 = bit.into();
println!("As an integer: {}", num);

Enums
