Remove element slice of struct pointers

It is not idiomatic and it is not okay usage. It should be:

SliceTricks

Delete (pointers)

copy(a[i:], a[i+1:])
a[len(a)-1] = nil // or the zero value of T
a = a[:len(a)-1]

For example,

package main

import (
    "fmt"
    "strconv"
)

const ARBITRARY = 5

type myData struct {
    det detailSlicePtr
}

type detail struct {
    id   int
    name string
}

// Slice of pointers to details
type detailSlicePtr []*detail

// Returns true if item removed succesfully,
// false all other cases
func (s *myData) remove(d *detail) bool {
    for i := range s.det {
        if s.det[i].name == d.name && s.det[i].id == d.id {
            copy(s.det[i:], s.det[i+1:])
            s.det[len(s.det)-1] = nil
            s.det = s.det[:len(s.det)-1]
            return true
        }
    }
    return false
}

// Find and remove a struct element from a slice of struct pointers within a     struct
func main() {

    var d myData
    details := make(detailSlicePtr, ARBITRARY)

    for j := 0; j < ARBITRARY; j++ {
        details[j] = &detail{
            id:   j,
            name: strconv.Itoa(j),
        }
    }

    d.det = details

    // Print out what we have so far
    for index := range d.det {
        fmt.Printf("Item %d is %s\n", index, d.det[index].name)
    }
    // Print what is hidden
    for i := range d.det[len(d.det):cap(d.det)] {
        j := len(d.det) + i
        det := d.det[:cap(d.det)]
        fmt.Printf("Hidden item %d is %v\n", j, det[j])
    }

    findMe := ARBITRARY / 2
    middle := &detail{id: findMe, name: strconv.Itoa(findMe)}

    if ok := d.remove(middle); !ok {

        fmt.Printf("Unable to find element: %v\n", middle)

    } else {

        fmt.Printf("Found and removed element: %v\n", middle)

        // Print what is left
        for index := range d.det {
            fmt.Printf("Item %d is %s\n", index, d.det[index].name)
        }
        // Print what is hidden
        for i := range d.det[len(d.det):cap(d.det)] {
            j := len(d.det) + i
            det := d.det[:cap(d.det)]
            fmt.Printf("Hidden item %d is %v\n", j, det[j])
        }
    }
}

Output:

Item 0 is 0
Item 1 is 1
Item 2 is 2
Item 3 is 3
Item 4 is 4
Found and removed element: &{2 2}
Item 0 is 0
Item 1 is 1
Item 2 is 3
Item 3 is 4
Hidden item 4 is <nil>

NOTE: There is a bug in the Slice Tricks that you linked to. It will be corrected soon. Until then use the link in my answer.
