• Golang: Sorting by Slice Fields 1 answer

I have a slice in golang which looks something like this.

list := []TripInfo{
        {
            TripID:  "uuid2",
            infov:true
        },
        {
            TripID:  "uuid1",
            infov:false
        },
    }

How can I sort it based on TripID so that it looks something like this?

list := []TripInfo{
        {
            TripID:  "uuid1",
            infov:false
        },
        {
            TripID:  "uuid2",
            infov:true
        },
    }

TripInfo is a struct

type TripInfo struct {
    TripUUID  string
    infov bool
}

The sort pkg is your friend:

import "sort"

// sort slice in place
sort.Slice(list, func(i, j int) bool {
    return list[i].TripID < list[j].TripID
})
