Working with the terminal UI (size, color, styles) and cursors

In this section, we will build the first iteration of the text viewer. At the end of this section, we will have a program that will accept a filename from the command line, display its contents, and display a header and footer bar. We will use a Termion crate to set the color and style, get the terminal size, position the cursor at specific coordinates, and clear the screen.

The code in this section is organized as follows:

Writing data structures and the main() function
Initializing the text viewer and getting the terminal size
Displaying a document and styling the terminal color, styles, and cursor position
Exiting the text viewer

Let's start with data structures and the main() function of the text viewer

Writing data structures and the main() function

In this section, we'll define the data structures needed to represent the text viewer in memory. We'll also write the...

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.
