Value type that represents a potentially missing value. This is similar to
System.Nullable<T>, but does not restrict the contained value to be a value
type, so it can be used for storing values of any types. When obtained from
DataFrame<R, C> or
Series<K, T>, the
Value will never be
(but this is not, in general, checked when constructing the value).
The type is only used in C#-friendly API. F# operations generally use expose
option<T> type instead. However, there the
contains helper functions for using this type from F# as well as
Present active patterns.
