Types

type Result

type Result[T, E any] struct {
	// contains filtered or unexported fields
}

Ok returns a Result that contains the given values.

func (Result[T, E]) Err

func (r Result[T, E]) Err() E

Err returns the error of the result. To be used after calling IsOK()

func (Result[T, E]) IsErr

func (r Result[T, E]) IsErr() bool

IsErr returns true if the result is not successful and has an error.

func (Result[T, E]) IsOk

func (r Result[T, E]) IsOk() bool

IsOk returns true if the result is successful with no error.
