Building a template engine

In this section, we will look at the design of an HTML template engine and implement one of the features using the Rust Standard Library. Let's first understand what a template engine is.

Applications such as web and mobile apps use structured data stored in datastores such as relational databases, NoSQL databases, and key-value stores. However, there is a lot of data on the web that is unstructured. One particular example is text data that all web pages contain. Web pages are generated as HTML files that have a text-based format.

On observing closely, we can see that an HTML page has two parts: static text literals and dynamic parts. The HTML page is authored as a template with the static and dynamic parts, and the context for HTML generation comes from a data source. While generating a web page, the generator should take the static text and output it without change, while it should combine some processing and the supplied context to generate...

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.
