Overview

The GOHELPER package provides utility functions for working with pointers and safely retrieving values from maps in Go. These helper functions can make your code cleaner and more concise.

Functions

Pointer Functions

These functions return pointers to values of their respective types. They are useful for creating pointer references for various data types.

Usage Example
go get github.com/tlabdotcom/gohelper

package main

import (
    "fmt"
    "github.com/google/uuid"
    "github.com/tlabdotcom/gohelper"
)

func main() {
    str := "Hello, World!"
    strPtr := gohelper.PointerString(str)
    fmt.Println(*strPtr) // Output: Hello, World!

    id := uuid.New()
    idPtr := gohelper.PointerUUID(id)
    fmt.Println(*idPtr) // Output: (some UUID value)
}
