Declare User Defined Data Types for Powerapps Canvas

Hi,

You can declare a user-defined time in the Formulas property similar to UDF and then use it in UDF . Please find a simple example below.

-----

//Record type

Point := Type({x: Number, y: Number});

// UDF to compute distance between two points

distance(a:Point,b:Point):Number = Sqrt(Power(b.x - a.x, 2) + Power(b.y-a.y, 2));

//Table type

Points := Type([Point]);

// UDF to check if the given table of points contains a particular point

containsPoint(points: Points, target:Point): Boolean = CountIf(points, ThisRecord.x = target.x && ThisRecord.y = target.y) > 0;

----

notice that you need to use := to declare user-defined type. Type is a special function used to construct a type definition.

I don't believe this is a general release feature yet.
