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.

Enumerations


If are you are used to C, you will be well used to enumerations, for example:

enum myEnum {start = 4, next, nextone, lastone=999};  

This creates an enum type that auto-fills next and nextone to be start + 1 and start + 2 respectively. If the first named parameter has nothing to give an initial value to, it is given the value 0 with everything after it being one larger than the last. They are accessed as myEnum.nextone.

An enum type in Rust has a very similar structure to a struct type, as shown in the following code:

enum MyEnum 
{ 
     TupleType(f32, i8, &str), 
     StructType { varone: i32, vartwo: f64 }, 
     NewTypeTuple(i32), 
     SomeVarName 
} 

As with C though, an enum is a single type, but the value of the enum can match any of its members.

Accessing enumeration members

Given the possibility of the contents of a Rust enum, you may be thinking that accessing one of the members within the enumeration may not be the simplest of tasks. Thankfully, it is, as an enum variable...
