wgpu::Texture -> wgpu::TextureView?

I have an wgpu::Texture; I want a wgpu::TextureView

Now, I see this function pub fn create_view(&self, desc: &TextureViewDescriptor<'_>) -> TextureView but I do not have a TextureViewDescriptor

Now, wgpu::Texture itself has a TextureViewDescriptor but it is not public

pub struct Texture {
    context: Arc<C>,
    id: ObjectId,
    data: Box<Data>,
    owned: bool,
    descriptor: TextureDescriptor<'static>,
}

Is there anyway to do wgpu::Texture -> wgpu::TextureView without forking the wgpu package ? I feel like I am missing something very very obvious.

TextureViewDescriptor should be public: TextureViewDescriptor in wgpu - Rust

The TextureViewDescriptor field of Texture is private:

pub struct Texture {
    context: Arc<C>,
    id: ObjectId,
    data: Box<Data>,
    owned: bool,
    descriptor: TextureDescriptor<'static>,
}

(Just browsing docs but) TextureViewDescriptor implements Default.

Incidentally if you search a type name, you can then click "In Return Types". That's how I found the implementation.

That field is a TextureDescriptor, not a TextureViewDescriptor. A single texture can be interpreted in multiple ways. It could be interpreted as a regular 2D image, as a cube map, as a 3D image and so on. You could use varying mipmap levels.You could have a single layer or multiple. And in the future it may be possible to interpret a texture as an srgb image at one time and a linearrgb image at another time. The TextureViewDescriptor describes how you want to interpret the texture for this specific texture view.

Ah, thank you. This stupid mistake on my part completely threw me off. Combined with @quinedot 's link to Default, everything makes sense now. Thanks!
