Is is possible to map from Option[T] to Option[S]?

[MyRaiser]

For example if we have:

• a variable t of type Option[T]
• a function fn of type func(T) S

And t.Map(fn) should be of type Option[S] . The Map() does something like this:

if t.IsSome() {
    return Some[S](fn(t))
}
return None[S]()

Is is possible?

this should have been possible. the actual map method in rust (ref) does it. but gust doesnt (ref)
Map should accept a func that takes a param T and returns S
a workaround could be

if t.IsSome() {
  return Some[S](fn(t.Unwrap()))
}
return None[S]()

Doing fn(t) means ur taking an Option as a param, not the inner value.
