How to implement code in rust to update the position x and y of the component with type length

Perhaps what you're looking for is to expose the x and y properties of an element to Rust. Properties of type length are mapped to f32 in Rust. For more information about the mappings, see the Type Mappings documentation. For information about how to expose properties and access them, check out the Generated components documentation.

How to deal with pixel units such as px, cm...

[tronical]

If you assign for example 2cm to a length property, we assume 96 pixels per inch, so "37.8 pixels" per cm and thus the f32 property would have a value of 75.5 in Rust/C++.

An idea, it would be great if slint supports it.

in property <int> pos-x: 0;
x: root.pos-x + "px";

[tronical]

Yes, this is doable by multiplication:

in property <int> pos-x: 0;
x: root.pos-x * 1px;
