-The next part of the shader code is the `main` function. We using `[[stage(vertex)]]` to mark this function as a valid entry point for a vertex shader. We expect a `u32` called `in_vertex_index` which gets its value from `[[builtin(vertex_index)]]`.

 We then declare a variable called `out` using our `VertexOutput` struct. We create two other variables for the `x`, and `y`, of a triangle.
