Overview ¶

Package result provides cross type transformations for `mo.Result`.

The functions provided by this package are not methods of `mo.Result` due to the lack of method type parameters on methods. This is part of the design decision of the Go's generics as explained here: https://go.googlesource.com/proposal/+/refs/heads/master/design/43651-type-parameters.md#No-parameterized-methods

Functions ¶

func FlatMap ¶

func FlatMap[I any, O any](f func(I) mo.Result[O]) func(result mo.Result[I]) mo.Result[O]

FlatMap returns the result of applying `f` to the value of result, if present, and None otherwise.

func FlatMatch ¶

func FlatMatch[I any, O any](onValue func(I) mo.Result[O], onError func() mo.Result[O]) func(result mo.Result[I]) mo.Result[O]

FlatMatch returns the result of applying `onValue` to the value of result, if present, or the result of `onError` if absent.

func Map ¶

func Map[I any, O any](f func(I) O) func(result mo.Result[I]) mo.Result[O]

Map returns a new `mo.Result` wrapping the result of applying `f` to the value of result, if present, and None otherwise.

func Match ¶

func Match[I any, O any](onValue func(I) (O, error), onError func() (O, error)) func(result mo.Result[I]) mo.Result[O]

Match returns a new `mo.Result` from the result of applying `onValue` to the value of result, if present, or from the result of calling `onError` if absent.
