Overview ¶
Package option provides cross type transformations for `mo.Option`.
The functions provided by this package are not methods of `mo.Option` 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 ¶
FlatMap returns the result of applying `f` to the value of opt, if present, and None otherwise.
func FlatMatch ¶
func FlatMatch[I any, O any](onValue func(I) mo.Option[O], onNone func() mo.Option[O]) func(opt mo.Option[I]) mo.Option[O]
FlatMatch returns the result of applying `onValue` to the value of opt, if present, or the result of `onNone` if absent.
func Map ¶
Map returns a new `mo.Option` wrapping the result of applying `f` to the value of opt, if present, and None otherwise.
func Match ¶
func Match[I any, O any](onValue func(I) (O, bool), onNone func() (O, bool)) func(opt mo.Option[I]) mo.Option[O]
Match returns a new `mo.Option` from the result of applying `onValue` to the value of opt, if present, or from the result of calling `onNone` if absent.
