Go Generics: The Clever Use of Generic Interfaces for Efficient and Adaptive Tree Structures
2025-07-10
This article explores advanced usage of Go's generic interfaces, particularly how to elegantly handle type constraints when building data structures like binary search trees using self-referential generic interfaces. Using a tree structure as an example, it compares three implementation approaches: using `cmp.Ordered`, a custom comparison function, and a self-referential generic interface. Finally, the article delves into combining `comparable` constraints to build ordered sets and avoiding complexities arising from pointer receivers, recommending prioritizing simplicity and readability in design.
