1//! ## fields
2//!
3//! * `min` maximum value.
4//! * `max` minimum value.
5//!
6//! ## Optional fields
7//!
8//! * `label`
9//! * `format` format string (in `printf` format)
10//! * `power`
11//! * `catch` override widget label.
12//! * `map` applies a mapping function to `&mut Self` (works the same as in the
13//!   [input example](../input/index.html#mapping))

15//! ## Example
16//!
17//! ```
18//! #[derive(imgui_ext::Gui)]
19//! struct Sliders {
20//!     #[imgui(slider(min = 0.0, max = 1.0))]
21//!     foo: f32,
22//!     #[imgui(slider(min = 0, max = 16, format = "bar = %.02f"))]
23//!     bar: [i32; 2],
24//! }
25//! ```
