Type Mappings
The types used for properties in .slint
design markup each translate to specific types in C++.
The follow table summarizes the entire mapping:

The unit are physical pixels. |

At run-time, logical lengths are automatically translated to physical pixels using the device pixel ratio. |

At run-time, durations are always represented as signed 64-bit integers with millisecond precision. |

Structures
For user-defined structures in the .slint code, a class
of the same name is generated with data member
in lexicographic order.
For example, if you have this structure in the .slint file
export struct MyStruct := {
foo: int,
bar: string,
}
It would result in the following type being generated:
class MyStruct {
public:
slint::SharedString bar;
int foo;
};
