A podcast for busy people who want to learn and quickly be productive with the Rust programming language.

Use Rust to develop a miniature version of the “sed” command-line utility, part 2. Covers topics that include an update to the level of detail covered in the podcast, considerations when selecting the name "build" or "new" for a constructor function that is associated with a "struct", differences between the Python Standard Library and Rust Standard Library when it comes to functionality for command-line interfaces and parsing command-line arguments, using "de-structuring" to create and assign values to multiple variables simultaneously, using the "clone" method to make a "deep copy", defining a custom "enum" type, several string-related methods (such as "split", "match_indices", and "split_at"), using "match" expressions, reading from standard input, using the "format!" macro to create new strings, and converting between "Strings" and "string slices".

#6 – minised, part 1
Use Rust to develop a miniature version of the “sed” command-line utility, part 1. Covers topics that include a subset of functionality for the “sed” command-line utility that’s used for replacing text, the scope of features that we’ll include in the miniature “sed” utility that we’re building, how to define a “struct” in Rust, how to leverage the “Option” enum for a value that may be either something or nothing, how to instantiate a “struct” in Rust via an associated function in an implementation block, how to bring a “struct” into scope in the binary crate, and how to use the “unwrap_or_else” method on a “Result” enum and define a “closure”.

#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.

#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".

#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.
