Function types that return interfaces in go

I’m trying to build a factory that constructs implementations of a given interface. To make adding new implementations of that interface easier, I’m trying to have the various implementations auto-register their constructors with the factory at init() time, but I can’t seem to figure out if it’s possible to make something like this. Here’s a… Read More Function types that return interfaces in go

Shared object reference between different Rust containers without copy

I want to have multiple data containers for the same object with the same reference (pointer), and can’t figure out how to achieve that in Rust. Go can simply use reference to the object as below: type container struct { id int status string } m1 := make(map[int]*container) m2 := make(map[int]*container) c := &container{id: 1,… Read More Shared object reference between different Rust containers without copy

Matching multiple unicode characters in Golang Regexp

As a simplified example, I want to get ^⬛+$ matched against ⬛⬛⬛ to yield a find match of ⬛⬛⬛. r := regexp.MustCompile("^⬛+$") matches := r.FindString("⬛️⬛️⬛️") fmt.Println(matches) But it doesn’t match successfully even though this would work with regular ASCII characters. I’m guessing there’s something I don’t know about Unicode matching, but I haven’t found any… Read More Matching multiple unicode characters in Golang Regexp
