Discriminated Unions | F# For Fun And Profit In f#, a sum type is called a “discriminated union” type. each component type (called a union case) must be tagged with a label (called a case identifier or tag) so that they can be told apart (“discriminated”). Discriminated unions are similar to union types in other languages, but there are differences. as with a union type in c or a variant type in visual basic, the data stored in the value is not fixed; it can be one of several distinct options.

Discriminated Unions | F# For Fun And Profit Today i've learned something about discriminated unions in f#. you use a du when you have to model an is a relationship. but first things first, how does such a relationship look like in an object oriented language like c#?. Throughout this article, we will take a look at what discriminated unions are, how they are defined, and some examples of how to use them in a f# project. I'm trying to understand how well c# and f# can play together. i've taken some code from the f# for fun & profit blog which performs basic validation returning a discriminated union type: type. In f#, a sum type is called a "discriminated union" type. each component type (called a union case) must be tagged with a label (called a case identifier or tag) so that they can be told apart ("discriminated").

Master discriminated unions in f# by solving 14 exercises, with support from our world class team. Both approaches can be used to create wrapper types around a string or other primitive type, so which way is better? the answer is generally the single case discriminated union. it is much easier to “wrap” and “unwrap”, as the “union case” is actually a proper constructor function in its own right. A discriminated union is defined using the type keyword, followed by the name of the discriminated union, and then a vertical bar (|) separated list of cases. let’s take a look at an example of a discriminated union that represents french playing cards:. This example does a great job illustrating not only simple, “dataless” unions but also shows how we can associate multiple data items and even combine discriminated unions to achieve more expressive code. we start by defining a discriminated union for each suit.
