func (Result[T]) And ¶

func (self Result[T]) And(res Result[T]) Result[T]

And return self if self is error, otherwise return other.

func (Result[T]) AsRawParts ¶ added in v0.2.1

func (self Result[T]) AsRawParts() (data T, err error)

AsRawParts return tuple of value ptr and error.

func (Result[T]) Error ¶

Error unwrap the error of the Result, panic if the Result is Ok.

func (Result[T]) IfErr ¶
