<\/span><\/h2>\nTo access the value stored within an option, you need to pattern match on the option type. Pattern matching allows you to destructure the option and handle both cases: when a value is present (`SOME`) and when it is absent (`NONE`).<\/p>\n
Here’s an example that demonstrates how to access the value in an option:
\n“`
\nval myOption = SOME 42; (* An option containing the value 42 *)<\/p>\n
case myOption of
\n NONE => print “No value present”
\n| SOME value => print (“The value is: ” ^ Int.toString value)
\n“`
\nIn this example, the `case` statement is used to pattern match on `myOption`. The first pattern `NONE` handles the case when `myOption` is `NONE`, and it simply prints a message indicating that no value is present. The second pattern `SOME value` handles the case when `myOption` is `SOME`, and it prints the value using the `Int.toString` function.<\/p>\n
