Combinators: map
match
is a valid method for handling Option
s. However, you may
eventually find heavy usage tedious, especially with operations only valid
with an input. In these cases, combinators can be used to
manage control flow in a modular fashion.
Option
has a built in method called map()
, a combinator for the simple
mapping of Some -> Some
and None -> None
. Multiple map()
calls can be
chained together for even more flexibility.
In the following example, process()
replaces all functions previous
to it while staying compact.
