flip

Routines for flipping slices in Go.

Usage

package main
import "github.com/go-flip/flip"
// IntSlice is equivalent to flip.IntSlice.
type IntSlice []int
// Len returns the length of the slice.
func (p IntSlice) Len() int {
    return len(p)
}
// Swap swaps the elements at the given indices.
func (p IntSlice) Swap(i, j int) {
    p[i], p[j] = p[j], p[i]
}
func main() {
    p := []int{1, 2, 3, 4}
    flip.Flip(IntSlice(p))
    fmt.Println(p)
}

flip can flip the contents of a slice by using the Len() and Swap() methods provided.
If a type already satisfies sort.Interface, it can be passed directly to flip.Flip.
Some interfaces for primitive slice types are implemented in the module.
See the documentation for available types.
