After completing the previous three in-depth articles on Rust iterators, in this article we will attempt to write our own Rust iterator, that is, to add iterator functionality to our own data. If any readers want to review the previous articles: In-Depth Rust Iterators (Part 1) In-Depth Rust Iterators (Part 2) In-Depth Rust Iterators (Part … Read more
@[TOC](Comprehensive Explanation of the C++ Standard Template Library (STL) – Everything You Need to Learn About STL) 1. Concept of STL 1. STL (Standard Template Library) is a generic term for the “containers + algorithms + iterators” in the C++ standard library, implemented using templates for generic programming. It evolved from HP’s STL and was … Read more
As a computer science student, I once learned about data structures, C language, linked lists, stacks, queues… But to be honest, over time, I almost forgot everything. This semester, I started learning C++, and I decided not to “grind through the textbooks” anymore, but to let GPT be my “companion AI tutor” to gradually rebuild … Read more
16. Decorators Decorators are Python’s “syntactic sugar” used to add additional functionality to functions without modifying the original function’s code (such as logging, timing, permission validation, etc.). 1. Basic Decorators # Define a decorator (essentially a function that takes another function as an argument) def log_decorator(func): def wrapper(*args, **kwargs): print(f"Starting execution of function: {func.__name__}") # … Read more
Getting Started with Rust Code (Part 5) This article mainly explains the control flow and iterators in Rust’s basic syntax. The control flow section covers conditional branches, loops, pattern matching, etc., while the iterators section progresses from basic concepts to custom iterators, explained step by step. During your learning process, don’t get too caught up … Read more
In-Depth Analysis of Rust Iterators: Principles, Chaining Calls, and Practical Applications In the world of Rust, iterators (Iterator) are not just a way to traverse data; they are a powerful programming paradigm that provides efficient, safe, and expressive tools for handling collection data. Understanding the underlying principles and advanced usage of iterators is essential for … Read more
Iterators are an important component of the STL. They act like a “navigator” for containers, allowing you to accurately traverse each element, whether you are dealing with a vector, list, or map. Learning STL requires mastering the basic usage of iterators, so let’s take a look. What exactly is an iterator? To illustrate, when you … Read more
In Python, iterables, iterators, and generators provide methods for generating data collections and for ordered traversal of data. If the amount of data generated is relatively small, it is recommended to use iterables; if the amount of data generated is large, it is recommended to use iterators or generators. Since the implementation of generators is … Read more

2 C++ Standard Library 2.1 Overview of the C++ Standard Library The above image outlines some components of the C++ Standard Library (SL), including algorithms, iterators, atomic operations, ranges, coroutines, input/output, thread support, and containers. It is important to note that most components are provided by the C++17 standard, with two provided by the C++20 … Read more
