In Go, what's the inverse of reflect.SliceOf()?
go, reflection
Solution
In your case, you already have the element type: `structField.Type()`. You can use `reflect.New(t).Elem()` to get an "editable" `reflect.Value` of a type. Once you've populated that value, you can call `slice.Index(i).Set(...)` to assign that value into the resulting slice.
To answer the letter of your question though, if you do have a slice and need to populate it, say you have a `reflect.Type` of a `[]int`, then you can call `.Elem()` to get the `reflect.Type` for `int`.
See the Type documentation for the methods you can call on a Type.
Problem
In Go, `reflect.SliceOf()` makes a Type representing a slice of the given Type: SliceOf returns the slice type with element type t. For example, if t represents int, SliceOf(t) represents []int. However, I already have a Type for `[]int` but want to get a Type for `int`. Is there an easy way to do that? (Note, I'm using `int` as an example. In reality, all I know is I have a slice, and I need to find what Type each element of the slice is.) I'm trying to populate a slice of bool, int, float, or string, from a `[]string` using reflection... here's the relevant piece: ``` numElems := len(req.Form["keyName"]) if structField.Kind() == reflect.Slice && numElems > 0 { slice := reflect.MakeSlice(structField.Type(), numElems, numElems) for i := 0; i < numElems; i++ { // I have some other code here to fill out the slice } } ``` But in order to fill out the slice, I need to know the type of the slice I'm filling out...
