1//! The conversions that keep setters short: what a setter of a property
2//! takes besides the value of the property itself (see
3//! [`IntoValue`](crate::builder::IntoValue)).
4//!
5//! | given                         | property value                     |
6//! |-------------------------------|------------------------------------|
7//! | `T`                           | `Option<T>`                        |
8//! | `&str`, `&String`             | `String`, `Option<String>`         |
9//! | an integer, `f64`             | `Option<String>` (its text)        |
10//! | an integer, `f32`             | `f64`                              |
11//! | `f64`, `(f64, f64)`, `(f64, f64, f64, f64)` | `Thickness`          |
12//! | `f64`                         | `CornerRadius`                     |
13//! | `Color`, a color name or `#rgb` text | `Option<Rc<dyn IBrush>>`    |
14//! | `&str`                        | `Option<BoxedValue>` (text content)|
15//!
16//! A color text that does not parse panics with the text: it is a mistake
17//! in the source, like an attribute XAML does not compile.
