//! ## fields
//!
//! * `min` maximum value.
//! * `max` minimum value.
//!
//! ## Optional fields
//!
//! * `label`
//! * `format` format string (in `printf` format)
//! * `power`
//! * `catch` override widget label.
//! * `map` applies a mapping function to `&mut Self` (works the same as in the
//!   [input example](../input/index.html#mapping))
//!
//! ## Example
//!
//! ```
//! #[derive(imgui_ext::Gui)]
//! struct Sliders {
//!     #[imgui(slider(min = 0.0, max = 1.0))]
//!     foo: f32,
//!     #[imgui(slider(min = 0, max = 16, format = "bar = %.02f"))]
//!     bar: [i32; 2],
//! }
//! ```
//!
//! ### Result
