opt<'T>

Namespace: Deedle

A type alias for the OptionalValue<T> type. The type alias can be used to make F# type definitions that use optional values directly more succinct.

`Value` Signature: 'T	Returns the value stored in the current `OptionalValue<T>`. Exceptions: `InvalidOperationException` - Thrown when `HasValue` is `false`.
`ValueOrDefault` Signature: 'T	Returns the value stored in the current `OptionalValue<T>` or the default value of the type `T` when a value is not present.

Static member	Description
`Missing` Signature: OptionalValue<'T>	Returns a new instance of `OptionalValue<T>` that does not contain a value.
