No More Nulls
Subject: Enumerated (enum) types, pattern matching, and meaningful return types.
Notes
Today’s episode discusses, in order:
Enumerated types, with an eye to the difference between structs and enums, and to the differences between enums in C and in Rust.
Pattern matching, with a focus on using them with enumerated types and some discussion about how they differ from switch blocks in C-like languages.
Using the Option and Result enumerated types with pattern matching to provide meaningful returns from functions safely.
Order
There is a specific order to the examples below, and it is not the automatically-alphabetized order rendered by rustdoc. Instead, you should work through in the sequence they appear in the source:
