Summary

In this chapter, we reviewed the overall structure of the Rust Standard Library and classified the modules of the standard library into different categories for better understanding. You got a brief introduction to the modules in areas of concurrency, memory management, file system operations, data processing, data types, error handling, compiler-related, FFI, networking, I/O, OS-specific, and time-related features.

We looked at what a template engine is, how it works, and defined the scope and requirements of our project. We designed the template engine in terms of Rust data structures (enum and struct) and Rust functions. We saw how to write code for parsing templates and to generate HTML for statements involving template variables. We executed the program providing input data and verified the generated HTML in the terminal (command line).

In the next chapter, we will take a closer look at the Rust Standard Library modules that deal with managing process environment...
