What is this?

[]int{1, 2, 3, 3}, []string{"1", "2", "3", "3"}, []float64{0.1, 0.2, 0.3, 0.3} etc.
You have to implement each type by yourself when removing duplicates from existing slices.
At that time, I made something that was put together and can be used even a little.

Installation

go get -u github.com/go-utils/dedupe

Usage

import (
"fmt""github.com/go-utils/dedupe"
)
funcmain() {
fmt.Println("[Case1]")
// Basic usagesliceString:= []string{"Go", "V", "C++", "Java", "Python", "Go", "Ruby", "C++", "Go", "V"}
dedupe.Do(&sliceString) // Be sure to pass it by addressfmt.Printf("original slice -> %#v\n\n", sliceString) // change original slicefmt.Println("[Case2]")
// Extract duplicates without changing the original slice// But: If it is a structure, you must cast it yourselfsliceFloat64:= []float64{0.1, 0.1, 0.2, 0.2, 0.3, 0.3}
dup:=dedupe.NewDeduplication() // or &dedupe.Deduplication{NotChange: true}dup.Do(&sliceFloat64) // Be sure to pass it by addressifsrc, err:=dup.Float64(); err==nil {
fmt.Printf("extracted slice -> %#v\n", src)
}
fmt.Printf("original slice -> %#v\n", sliceFloat64)
}

Result

[Case1]
original slice -> []string{"C++", "Go", "Java", "Python", "Ruby", "V"}
[Case2]
extracted slice -> []float64{0.1, 0.2, 0.3}
original slice -> []float64{0.1, 0.1, 0.2, 0.2, 0.3, 0.3}
