Functions

f filter	Returns `None` if the `option` is `None`, otherwise calls predicate with the wrapped value and returns: `Some` if predicate returns `true`. `None` if predicate returns `false`.
f flat	Converts from `Option<Option<T>>` to `Option<T>`.
f map	Maps an `Option<T>` to `Option<U>` by applying a function to a contained value(if `Some`) or returns `None`(if `None`).
f mapOr	Returns the provided default value (if `None`), or applies a function to the contained value (if `Some`).
f mapOrElse	Computes a default function result (if `None`), or applies a different function to the contained value (if `Some`).
f zip	Zips `option` with another `Option`.
