Check whether a string slice contains a certain value in Go

Question

What is the best way to check whether a certain value is in a string slice? I would use a Set in other languages, but Go doesn\'t have one.

My best try is this so far:

Answer 1

You can use a map, and have the value e.g. a bool

m := map[string] bool {"a":true, "b":true, "x":true}
if m["a"] { // will be false if "a" is not in the map
    //it was in the map
}

There's also the sort package, so you could sort and binary search your slices
