func (Option[T]) UnwrapOrElse ¶
func (o Option[T]) UnwrapOrElse(fn func() T) T
type Result ¶
type Result[T any] struct { // contains filtered or unexported fields }
Result[T] is a generic pseudo-enum, used for returning results with errors. The result type eliminates the need to return nil pointers, sentinal type zero values, or partial results when an error has occured. Instead, the result type can be in one of two states: Ok(T) or Err(error).
func NewPtrResult ¶
func NewTupleResult ¶
func NewVoidResult ¶
func (Result[T]) ResultsMappingEmpty ¶
ResultsMapEmpty maps the None case of the result value to an empty T (instead of a nil pointer to a T as is done by `Results()`)
func (Result[T]) UnwrapErrOr ¶
func (Result[T]) UnwrapOrElse ¶
