Rust for Rustaceans
Author: Jon Gjengset
Publisher: No Starch Press
ISBN: 1718501862
Category : Computers
Languages : en
Pages : 282
Book Description
Master professional-level coding in Rust. For developers who’ve mastered the basics, this book is the next step on your way to professional-level programming in Rust. It covers everything you need to build and maintain larger code bases, write powerful and flexible applications and libraries, and confidently expand the scope and complexity of your projects. Author Jon Gjengset takes you deep into the Rust programming language, dissecting core topics like ownership, traits, concurrency, and unsafe code. You’ll explore key concepts like type layout and trait coherence, delve into the inner workings of concurrent programming and asynchrony with async/await, and take a tour of the world of no_std programming. Gjengset also provides expert guidance on API design, testing strategies, and error handling, and will help develop your understanding of foreign function interfaces, object safety, procedural macros, and much more. You'll Learn: How to design reliable, idiomatic, and ergonomic Rust programs based on best principles Effective use of declarative and procedural macros, and the difference between them How asynchrony works in Rust – all the way from the Pin and Waker types used in manual implementations of Futures, to how async/await saves you from thinking about most of those words What it means for code to be unsafe, and best practices for writing and interacting with unsafe functions and traits How to organize and configure more complex Rust projects so that they integrate nicely with the rest of the ecosystem How to write Rust code that can interoperate with non-Rust libraries and systems, or run in constrained and embedded environments Brimming with practical, pragmatic insights that you can immediately apply, Rust for Rustaceans helps you do more with Rust, while also teaching you its underlying mechanisms.

Publisher: No Starch Press
ISBN: 1718501056
Category : Computers
Languages : en
Pages : 273
Book Description
A detailed introduction to the C programming language for experienced programmers. The world runs on code written in the C programming language, yet most schools begin the curriculum with Python or Java. Effective C bridges this gap and brings C into the modern era--covering the modern C17 Standard as well as potential C2x features. With the aid of this instant classic, you'll soon be writing professional, portable, and secure C programs to power robust systems and solve real-world problems. Robert C. Seacord introduces C and the C Standard Library while addressing best practices, common errors, and open debates in the C community. Developed together with other C Standards committee experts, Effective C will teach you how to debug, test, and analyze C programs. You'll benefit from Seacord's concise explanations of C language constructs and behaviors, and from his 40 years of coding experience. You'll learn: How to identify and handle undefined behavior in a C program The range and representations of integers and floating-point values How dynamic memory allocation works and how to use nonstandard functions How to use character encodings and types How to perform I/O with terminals and filesystems using C Standard streams and POSIX file descriptors How to understand the C compiler's translation phases and the role of the preprocessor How to test, debug, and analyze C programs Effective C will teach you how to write professional, secure, and portable C code that will stand the test of time and help strengthen the foundation of the computing world.

C for Java Programmers
Author: Tomasz Müldner
Publisher: Addison-Wesley
ISBN:
Category : Computers
Languages : en
Pages : 632
Book Description
The C programming language has been around for over 25 years. Lately, however, more and more programmers are learning Java as their first language. While Java offers many advantages, C is more efficient and appropriate when working with certain run-time applications, compilers, graphics and operating systems. With C for Java Programmers, Tomasz M, ldner adopts an innovative approach modern ANSI C techniques to readers already familiar the Java concepts. He takes advantage of the techniques and underlying design principles present in object-oriented languages like Java and incorporates them to create a set of programming standards applicable to C. These standards are present throughout each chapter both in short examples and in longer modules. C for Java Programmers centers around such vital concepts as the ability to extend and modify modules, represent enumerations, create concrete and generic modules, and use shallow and deep copying of data elements. In addition, this book provides a thorough discussion of issues such as memory management, pointer use, and exception handling--topics traditionally more troublesome for novice C programmers--which become increasingly important in the less-protected world of C. 0201702797B04062001
