TryValue<'T>

Namespace: Deedle

Represents a value or an exception. This type is used by functions such as Series.tryMap and Frame.tryMap to capture the result of a lambda function, which may be either a value or an exception. The type is a discriminated union, so it can be processed using F# pattern matching, or using Value, HasValue and Exception properties
