Implementing a dynamic data structure

In this section, we will enhance the template engine from Chapter 3, Introduction to the Rust Standard Library and Key Crates for Systems Programming, to add support for multiple template variables in one statement. We will achieve this by converting a static data structure into a dynamic data structure.

We will refresh our memory with the model of the template engine shown in Figure 5.7:

Figure 5.7 – Conceptual model of the template engine (from Chapter 3, Introduction to the Rust Standard Library and Key Crates for Systems Programming)

Figure 5.7 – Conceptual model of the template engine (from Chapter 3, Introduction to the Rust Standard Library and Key Crates for Systems Programming)

You will recall that we implemented a template engine in Chapter 3, Introduction to the Rust Standard Library and Key Crates for Systems Programming, to parse an input statement with a template variable and convert it into a dynamic HTML statement using context data provided. We will enhance the template variable feature in this section. We will first discuss the design changes...

Hands-On Concurrency with Rust

Hands-On Concurrency with Rust

Writing safe and correct parallel programs is tough. Reasoning about concurrent memory modification is tough; efficiently exploiting the modern computing environment (with its multi-layered caches and deep execution pipelines) is also tough. Most systems programming languages add a further complication: unsafe memory access. The burden on you, the programmer, lies across two domains: understanding the modern machine and understanding your language's pain-points. Rust, with its safe memory model and strong type system, eases this last burden without sacrificing performance. This book will teach you to reason about program performance on modern machines and build fast, memory-safe, and concurrent software in Rust.
