4//! * `min` maximum value
5//! * `max` minmum value
6//! * `speed`
7//! * `power`
8//! * `format` (format string in `printf` format)
9//! * `catch` override widget label.
10//! * `map` Applies a mapping function to `&mut Self` (works the same as in the
11//!   [input example](../input/index.html#mapping))
