What is this?

If you want to know if "Hello" is included in "Hello, World!", Use string.Contains("Hello, World!","Hello").
If you want to know whether "1" is included in []string{"1", "2", "3"}, you have to implement it yourself.
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/cont

Usage

import (
"fmt""time""github.com/go-utils/cont"
)
funcmain() {
ifcont.Contains([]string{"1", "2", "3"}, "1") {
fmt.Println("ex1: OK!")
}
ifcont.Contains([]int{1, 2, 3}, 1) {
fmt.Println("ex2: OK!")
}
ifcont.Contains("123", "1") {
fmt.Println("ex3: OK!")
}
now:=time.Now()
mp:=map[string]interface{}{"a": "1", "b": 2, "c": "3", "d": now}
ifcont.Contains(mp, now) {
fmt.Println("ex4: OK!")
}
ifcont.Contains(mp, 2) {
fmt.Println("ex5: OK!")
}
ifcont.Contains(mp, "c") {
fmt.Println("ex6: OK!")
}
}

Result

ex1: OK!
ex2: OK!
ex3: OK!
ex4: OK!
ex5: OK!
ex6: OK!
