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 Zero ¶

func Zero[T any]() T

Returns the zero value of type T

Types ¶

type AnyIOFunc ¶

type AnyIOFunc interface {
	AnyZeroHelper

	// If type assertion fails, implementation should still call the
	// underlying function with the zero value of the input type.
	ExecuteLoose(any) (any, error)

	// If type assertion fails, implementation should return an error
	// and the zero value of the input type, without calling the
	// underlying function.
	ExecuteStrict(any) (any, error)
}

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 IOFunc ¶

type IOFunc[I any, O any] func(I) (O, error)

func (IOFunc[I, O]) ExecuteLoose ¶

func (ioFunc IOFunc[I, O]) ExecuteLoose(input any) (any, error)

If type assertion fails, ExecuteLoose will still call the underlying function with the zero value of the input type.

func (IOFunc[I, O]) ExecuteStrict ¶

func (ioFunc IOFunc[I, O]) ExecuteStrict(input any) (any, error)

If type assertion fails, ExecuteStrict will return an error and the zero value of the input type, without calling the underlying function.

func (IOFunc[I, O]) I ¶

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

func (IOFunc[I, O]) IPtr ¶

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

func (IOFunc[I, O]) O ¶

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

func (IOFunc[I, O]) OPtr ¶

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

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
