Episodes

#1 – Introduction

Introduction episode for the Learning Rust For Busy People podcast.

#2 – Installing Rust and using Cargo to manage a project

Overview of installing Rust and using Cargo to create a new project, compile code, and run the executable that’s built. Discussion of differences and similarities in how projects are set up and managed in Rust versus in Python.

#3 – Extracting text from a Markdown file, part 1

First practical code example. Use Rust to extract text from a Markdown file. Covers how to use Rust to read the contents of a text file, iterate through lines of a text file, manipulate a String by replacing text, and print the value of a variable to standard output.

Code example: version 1

#4 – Extracting text from a Markdown file, part 2

Use Rust to extract text from a Markdown file, part 2. Covers concepts that include refactoring a program into a binary crate and a library crate for separation of concerns, passing command-line arguments to a program, using a vector, using the “dbg!” macro, the system of “ownership” in Rust, and what it means for a Rust program to “panic”.

Code example: version 2

#5 – Extracting text from a Markdown file, part 3

Use Rust to extract text from a Markdown file, part 3. Covers concepts that include how to implement error handling by treating problems as either “unrecoverable” errors (by calling the “panic!” macro) or “recoverable” errors (by returning a “Result” enum), how to propagate errors using the question mark operator, and how to specify return types and return values for functions.

Code example: version 3
