Functions ¶

func AssertOrZero ¶

func AssertOrZero[T any](v any) T

Returns v cast as type T if possible, otherwise returns the zero value of T

func IsNone ¶

func IsNone(v any) bool

Returns true if v is either an empty struct or a pointer to an empty struct

func OrDefault ¶

func OrDefault[F comparable](field F, defaultVal F) F

Returns field if it is not the zero value for its type, otherwise returns defaultVal

func Zero ¶

func Zero[T any]() T

Returns the zero value of type T

Types ¶

type AnyZeroHelper ¶

type AnyZeroHelper interface {
	I() any    // returns direct I zero val
	O() any    // returns direct O zero val
	IPtr() any // returns `new(I)` (pointer to I)
	OPtr() any // returns `new(O)` (pointer to O)
}

type None ¶

type None = struct{}

Simple alias for an empty struct

type ZeroHelper ¶

type ZeroHelper[I any, O any] struct{}

func (ZeroHelper[I, O]) I ¶

func (ZeroHelper[I, O]) I() any

func (ZeroHelper[I, O]) IPtr ¶

func (ZeroHelper[I, O]) IPtr() any

func (ZeroHelper[I, O]) O ¶

func (ZeroHelper[I, O]) O() any

func (ZeroHelper[I, O]) OPtr ¶

func (ZeroHelper[I, O]) OPtr() any
