Is it possible to instantiate a struct from other members?

[camprevail]

Here's what I'm trying to do:

struct Rect {
    float left, right, top, bottom;
};

struct Data {
    if (dataInfo.vertex_offset) {
        Point vertexPoints[dataInfo.vertex_count] @ dataInfo.vertex_offset;
    }
    if (geo_has_bounds_floats) {
        Rect bounds;
    } else if (vertex_well_formed_rectangle) {
------->Rect bounds = vertexPoints[0].x, vertexPoints[1].x, vertexPoints[0].y, vertexPoints[2].y; 
    }
}; Data data @ $;

I can't figure out how to create a Rect object from previously defined items. Is this even possible? Or do structs only work on file read operations

No, you can create local variables that are not placed, but assigning to them can be done for example by having a function that returns the type so you can assign it.That works in theory but in practice there are some problems with local function custom types and doesn't always work as expected.
