ptrutils

Pointer utilities for safe pointer operations and conversions.

Overview

The ptrutils package (imported as ptr) provides utilities for working with pointers, including creating pointers to literals, safe dereferencing, and pointer slice operations.

Functions

Creation: To Dereferencing: Deref, DerefSlice Comparison: Equal, IsNil Utilities: Coalesce, ToSlice, NonNilSlice, ToPointerSlice

import ptr "github.com/Goldziher/go-utils/ptrutils"

// Create pointers to literals
numPtr := ptr.To(42)
strPtr := ptr.To("hello")

// Safe dereferencing with default
value := ptr.Deref(numPtr, 0)  // 42
nilValue := ptr.Deref((*int)(nil), 99)  // 99

// Coalesce - get first non-nil
first := ptr.Coalesce(nil, nil, ptr.To(5), ptr.To(10))  // *5

// Convert slice to pointer slice
values := []int{1, 2, 3}
ptrs := ptr.ToPointerSlice(values)  // []*int
