Functions

func From

func From[T any](p *T) (zero T)

From dereferences a pointer by returning the zero value if null

func IsInterfaceNil

func IsInterfaceNil(i any) bool

IsInterfaceNil checks if either an interface or it's underlying concrete value is nil. If the type can't be nil, it return's false.

func Or

func Or[T comparable](vals ...T) T

Or returns the first of its arguments that is not equal to the zero value. If no argument is non-zero, it returns the zero value. Essentially cmp.Or that rejects nil interfaces.

func To

func To[T any](s T) *T

To returns a pointer to value
