Performance doesn't always matter
The tutorial 'Learning Rust With Entirely Too Many Linked Lists' is provided by Alexis Beingessner, also known as Gankro. It is hosted on a personal website, indicating that it's an independently created resource by an individual passionate about Rust programming. The informal tone and unique approach to teaching suggest a developer-to-developer style of instruction.
This tutorial focuses on teaching Rust programming language concepts through the implementation of linked lists. It takes an unconventional approach by creating multiple versions of linked lists, each introducing new Rust concepts and best practices. The course likely covers memory management, ownership, borrowing, and other core Rust features while building increasingly complex data structures.
