Sorting by slice fields

Question

I have the following Structs:

type Parent struct {
    id       string
    children []Child
}

type Child struct {
    id string
}

I have m

Answer 1

I got it to work using the following code:

// sort each Parent in the parents slice by Id
sort.Slice(parents, func(i, j int) bool {return parents[i].id < parents[j].id})

// for each Parent, sort each Child in the children slice by Id
for _, parent := range parents {
    sort.Slice(parent.children, func(i, j int) bool {return parent.children[i].id < parent.children[j].id})
}

Special thanks to @Volker for mentioning the sort.Slice function! I had no idea it existed!
