В этой главе курса по Rust мы разбираем базовые типы данных: числа с разной знаковостью и размером, строки String и &str, булевы значения, кортежи и массивы. Показаны практические примеры использования и поясняется, когда и как применять эти типы в коде. 🚀
В этой главе курса по Rust мы изучаем, как управлять потоком выполнения программы. Вы узнаете, как работают конструкции if, else, оператор match для сопоставления с образцом, а также циклы loop, while и for. Всё сопровождается понятными примерами кода и объяснениями. 🚀
В первой главе курса по Rust мы рассмотрим основные особенности языка, его преимущества и недостатки, а также сферы применения. Подробно разберём процесс установки Rust на различные операционные системы. Если вы только начинаете изучать Rust, этот материал поможет вам разобраться в основах и сделать первый шаг в программировании на Rust. 🚀
Во второй главе курса по Rust мы рассмотрим структуру программы, разберём процесс компиляции и запуска кода. Также познакомимся с Cargo — мощным инструментом для управления проектами на Rust. Узнаем, как создавать, собирать и запускать проекты с его помощью. 🚀
В этой главе курса по Rust мы рассмотрим переменные и константы. Разберём ключевые концепции: let, mut, const, static, а также затенение переменных (shadowing). Узнаем, как правильно управлять изменяемостью данных и избегать ошибок. 🚀
Flutter does not have native 3D rendering support out-of-the-box, but it can be extended to render 3D graphics using external libraries and plugins. To build a Three.js-like 3D library for Flutter, we need to consider existing solutions, rendering technologies (WebGL, Vulkan, OpenGL), language interoperability, performance, and cross-platform challenges. Below is a structured overview of how such a library can be implemented, including current tools, best practices, and recommendations.
When working with Python, you often encounter scenarios where merging dictionaries is required. However, a simple update() or dictionary unpacking ({**dict1, **dict2}) might not suffice when dictionaries contain nested structures. This is where a recursive merge function becomes incredibly useful. In this blog, we’ll explore a Python function, merge_dicts, that merges two dictionaries recursively
Asynchronous programming is a powerful feature of C# that allows for efficient execution of operations, particularly those that involve long-running tasks or IO-bound work, such as file operations, database transactions, or network requests. By using asynchronous programming, you can keep your application responsive and improve its overall performance by not blocking the main thread while waiting for operations to complete. This chapter introduces the basics of asynchronous programming in C# using async and await keywords, and explores how to perform asynchronous operations with tasks.
File handling is an essential aspect of many C# applications, enabling you to create, read, update, and delete files on the filesystem. C# provides a comprehensive set of classes in the System.IO namespace for working with files and directories, making file operations straightforward and efficient. This chapter covers the basics of file handling in C#, including how to work with files and directories, read and write files, and handle file I/O operations securely and efficiently.
Entity Framework (EF) is an open-source object-relational mapping (ORM) framework for ADO.NET, part of the .NET ecosystem. It serves as a bridge between the relational database world and the object-oriented world of .NET, allowing developers to work with data in the form of domain-specific objects and properties, without having to deal with the underlying database tables and columns directly. This chapter introduces the basics of Entity Framework, covering its two main approaches: Code-First and Database-First, and how to perform CRUD (Create, Read, Update, Delete) operations.
Encapsulation is a fundamental concept in object-oriented programming (OOP) that involves bundling the data (attributes) and methods (functions) that operate on the data into a single unit, known as a class. It also restricts direct access to some of the object's components, which is a way of preventing accidental manipulation of data and ensuring internal data integrity. This principle of hiding the internal state and requiring all interaction to occur through an object's methods is central to C#. This chapter explains the concept of encapsulation and demonstrates how to implement it in C# through access modifiers and properties.
In C#, delegates and events are foundational concepts that enable a flexible and extensible way to handle method callbacks and notifications. They play a crucial role in designing and implementing event-driven programming patterns, which are central to developing interactive applications such as graphical user interfaces, game development, and service-oriented applications. This chapter introduces delegates and events, explaining their uses, syntax, and how they enable managed event handling in C#.
