Two things to note here:
Several things to note here:
1. Here you can specify which function inside the shader should be the `entry_point`. These are the functions we marked with `[[stage(vertex)]]` and `[[stage(fragment)]]`
2. The `buffers` field tells `wgpu` what type of vertices we want to pass to the vertex shader. We're specifying the vertices in the vertex shader itself, so we'll leave this empty. We'll put something there in the next tutorial.
3. The `fragment` is technically optional, so you have to wrap it in `Some()`. We need it if we want to store color data to the `surface`.
4. The `targets` field tells `wgpu` what color outputs it should set up.Currently, we only need one for the `surface`. We use the `surface`'s format so that copying to it is easy, and we specify that the blending should just replace old pixel data with new data. We also tell `wgpu` to write to all colors: red, blue, green, and alpha. *We'll talk more about*`color_state` *when we talk about textures.*

While this is definitely nice, Rust sees the result of `vertex_attr_array` is a temporary value, so a tweak is required to return it from a function. We could change the lifetime on `wgpu::VertexBufferLayout` to `'static`, or [make it `const`](https://github.com/gfx-rs/wgpu/discussions/1790#discussioncomment-1160378). You can see an example below:
