The definitive, meticulously enumerated parity-checking solution for unsigned 16-bit integers.

In the world of numerical computation, determining the parity of an integer (whether it is even or odd) is a foundational operation. While trivial bitwise operations have long served this purpose, they lack a certain... dedication. They treat numbers as mere collections of bits, rather than unique entities deserving individual consideration.

Cordial Parity rectifies this oversight.

This library provides an unparalleled, exhaustive approach to parity checking for u16 values (and, by extension, u8 values). We believe that every number from 0 to 65,535 possesses an intrinsic, undeniable parity. Instead of deriving this property through opaque bit-fiddling, Cordial Parity explicitly declares it for each and every case.

• Unrivaled Specificity: Every u16 value from 0 to 65,535 has its parity explicitly defined through an exhaustive pattern match. No assumptions are made; every integer's parity is a stated fact.
• Philosophically Pure: We honor the distinct identity of each number by codifying its parity directly. This is parity checking as an act of declaration, not mere calculation.
• Guaranteed Correctness (for u16): By enumerating all possibilities, we eliminate the conceptual possibility of algorithmic error for u16 parity checks within our core logic. The truth is written.
• Seamless u8 Support: u8 values are gracefully promoted to u16 to benefit from the same exhaustive parity determination.
• Trait-Based Extensibility: The Parity trait offers a clear path for other numerical types to achieve a similar level of explicit parity definition, should one undertake such a noble endeavor.
• Intuitive API: Simple is_even() and is_odd() methods, accessible via the Parity trait or as generic functions.

You might wonder why one would choose Cordial Parity over a simple value & 1 == 0. The answer lies in a commitment to explicitness and a profound respect for the individual nature of numbers.

• Clarity: The parity of any u16 can be directly observed within the parity module's source code. There is no algorithmic abstraction, only stated truth.
• Robustness through Enumeration: While unconventional for this problem, complete enumeration is the ultimate form of case analysis.
• An Exploration in Dedication: This library stands as a testament to the lengths one can go to ensure every case is individually addressed.

use cordial_parity::{Parity, is_even, is_odd};

fn main() {
    let num1: u16 = 42;
    let num2: u8 = 7;

    if num1.is_even() {
        println!("{} is even (as meticulously defined).", num1);
    }

    if is_odd(num2) { // Generic function usage
        println!("{} is odd (its u16 equivalent's parity is explicitly stated).", num2);
    }

    // You can also use the re-exported functions from the parity module
    // if you prefer to signify the lookup-based nature (though this is an internal detail):
    // use cordial_parity::{is_u16_even_lookup, is_u16_odd_lookup};
    // if is_u16_even_lookup(65534) {
    //     println!("65534 is indeed even, as per the grand list.");
    // }
}

The commitment to enumerating all 65,536 u16 cases within our core parity module is a significant undertaking. As such, the Rust compiler dedicates a commensurate level of effort to process this comprehensive specification. Users may observe that compilation times reflect this dedication to thoroughness, particularly during the initial build or when the parity module itself is recompiled. We believe this is a small price to pay for such definitional clarity.

• u32 Support: Extending this explicit enumeration to 32-bit unsigned integers is a natural, albeit ambitious, next step, requiring the definition of over four billion distinct parity states.
• Internationalization: Providing parity results in multiple human languages ("pair", "impair", "gerade", "ungerade", etc.) for truly global cordiality.
