How to ignore attributes/children when deserializing? about serde-xml-rs HOT 4 OPEN

Thank you @Boscop !
For google streetview images, I am not familiar with the format, but it looks like the kind of things that dezoomify-rs's generic dezoomer handles.

I think this might be a duplicate of #3 .

This small example you have shown should definitely not require multiple GB of RAM

@Boscop : Hello ! I know I am 3 years late, but I stumbled upon this issue, and it looks like you were trying to parse krpano description files in rust. I am the maintainer of dezoomify-rs, which also contains a (currently incomplete) implementation of the krpano xml format in rust. Can you tell a little bit more on what your project was at the time, and if you happen to still have an open-source implementation of a KRPano XML parser in rust ?

@lovasoa Wow, I didn't know about dezoomify but it looks like a very cool project.
That project was about downloading 360° panorama/cubemap tiles and stitching them together, to be able to load them as cubemaps with glium like this.
I just looked at the code (that I haven't run since then, because I've been busy with other things, but at some point I might get back to it).
I vaguely remember that after I added explicit enum variants for all the cases that can occur, it worked.
These are the structs I ended up using, but they are incomplete as well, stuffing all the attributes into Vec<String>s. Feel free to use this & build on this:

#[derive(Debug, Deserialize)]
struct KrPano {
	#[serde(rename = "$value")]
	items: Vec<KrPanoItems>,
}

#[derive(Debug, Deserialize)]
#[allow(non_camel_case_types)]
enum KrPanoItems {
	panoview(Vec<String>),
	view(Vec<String>),
	autorotate(Vec<String>),
	image(Image),
	action(Vec<String>),
	layer(Vec<String>),
}

#[derive(Debug, Deserialize)]
struct Image {
	#[serde(rename = "type")]
	typ: String,
	multires: bool,
	right: Side,
	left: Side,
	up: Side,
	down: Side,
	front: Side,
	back: Side,
}

#[derive(Debug, Deserialize)]
struct Side {
	url: String,
}

Btw, could you add support for downloading tiles from google streetview panoramas? :)

Some example code here:

E.g.

But depending on the size, it needs to be cropped:
