UniquePtr

The UniquePtr library in Rust is inspired by the unique_ptr smart pointer in C++. Both implementations share the same fundamental purpose: providing unique ownership of dynamically allocated objects and ensuring proper deallocation.

Here are some key similarities and differences between the two:

1. Unique Ownership: Both UniquePtr in Rust and unique_ptr in C++ enforce exclusive ownership of the managed object. This means that only one smart pointer instance can own and manage the object at any given time.
2. Automatic Deallocation: When the UniquePtr or unique_ptr instance goes out of scope or is explicitly reset, they automatically deallocate the managed object, freeing the associated memory.

Usage

use unique_ptr::UniquePtr;

fn main() {
    let ptr = Box::new(42);
    let unique_ptr = UniquePtr::with_ptr(ptr);

    assert_eq!(unsafe { *unique_ptr.ptr }, 42);

    let ptr2 = Box::new(99);
    unique_ptr.reset(ptr2);

    assert_eq!(unsafe { *unique_ptr.ptr }, 99);
}

Features

• Supports Clone.
• Supports Deref and DerefMut.
• Can be used with any type that implements the Drop trait.
• Supports custom deleters using the Deleter type parameter.

• Implements common smart pointer operations such as resetting the pointer, releasing ownership, cloning the pointer, and dereferencing.
• Provides a safe interfacefor working with raw pointers.
