Overview

Package pointer provides helper functions related to Go pointers.

Functions

func Copy

func Copy[A any](a *A) *A

Copy returns a new pointer to a.

func Eq

func Eq[P Primitive](a, b *P) bool

Eq returns whether a and b are equal in underlying value.

May only be used on pointers to primitive types, where the comparison is guaranteed to be sensible. For complex types (i.e. structs) consider implementing an Equals method.

func Merge

func Merge[P Primitive](previous, next *P) *P

Merge will return Copy(next) if next is not nil, otherwise return Copy(previous).

func Of

func Of[A any](a A) *A

Of returns a pointer to a.

Types

type Primitive

type Primitive interface {
	constraints.Ordered | bool
}

Primitive represents basic types that are safe to do basic comparisons by pointer dereference (checking nullity first).
