Types

type OrErr

type OrErr[V any] struct {
	// contains filtered or unexported fields
}

An OrErr[V] bundles a value of type V with a possibly-nil error. This allows the user to pass around a single value instead of dealing with tuples.

Values can be extracted with Get; callers should check the error as with any other method that returns an error.

func New

func New[V any](value V, err error) OrErr[V]

New bundles a value and possible error in an OrErr.

func (OrErr[V]) Err

func (t OrErr[V]) Err() error

Err returns the error from the OrErr.

func (OrErr[V]) Get

func (t OrErr[V]) Get() (V, error)

Get gets the components of the T.
