Learning Rust

By: Vesa Kaihlavirta

Overview of this book

Rust is a highly concurrent and high performance language that focuses on safety and speed, memory management, and writing clean code. It also guarantees thread safety, and its aim is to improve the performance of existing applications. Its potential is shown by the fact that it has been backed by Mozilla to solve the critical problem of concurrency. Learning Rust will teach you to build concurrent, fast, and robust applications. From learning the basic syntax to writing complex functions, this book will is your one stop guide to get up to speed with the fundamentals of Rust programming. We will cover the essentials of the language, including variables, procedures, output, compiling, installing, and memory handling. You will learn how to write object-oriented code, work with generics, conduct pattern matching, and build macros. You will get to know how to communicate with users and other services, as well as getting to grips with generics, scoping, and more advanced conditions. You will also discover how to extend the compilation unit in Rust. By the end of this book, you will be able to create a complex application in Rust to move forward with.

The standard modules


With the overviews done, let's look at the standard modules.

std::Any

This module enables the dynamic casting of 'static via runtime reflection.

Note

It can be used to obtain a TypeId. When used as a borrowed trait reference (&Any), it can be used to determine whether the value is a given type (using Is) and also to get a reference to the inner value as a type (using downcast_ref). &mut Any will allow access to downcast_mut, which obtains the mutable reference to the inner value. &Any can only be used for testing a specific type and cannot be used to test whether a type implements a trait.

Structs

  • TypeId: TypeId is an opaque object that cannot be examined, but does allow for clone, compare, print, and show. Only available for types that use 'static.

Implement

  • of<T>() -> TypeId where T:’static + Reflect + ?Sized: This returns the TypeId of the type T the function was instantiated with.

Traits

  • pub trait Any: 'static + Reflect {fn get_type_id(&self) -&gt...
