Detailed Description

An integer option represents either an integer or nothing.

Option types are typically used with functions that may return a value of the given type or nothing (i.e. the return value is optional). The none member is true if the value is not present. Otherwise the value can be accessed with the some member.

Example:

IntOption op = index_of_int_value(array, 123); // index of value 123?
if (op.none) {
    printsln("value not found");
} else {
    printiln(op.some);
}
