paginator.rs

//! A paginator component for bubbletea-rs, ported from the Go version.
//!
//! This component is used for calculating pagination and rendering pagination info.
//! Note that this package does not render actual pages of content; it's purely
//! for handling the state and view of the pagination control itself.

/// A paginator model for handling pagination state and rendering.
///
/// This component manages pagination state including current page, total pages,
/// and pagination display style. It can render pagination in two modes:
/// - **Arabic**: Shows page numbers (e.g., "3/10")
/// - **Dots**: Shows dots representing pages (e.g., "○ ○ ● ○ ○")
///
/// The paginator handles key bindings for navigation and provides helper methods
/// for calculating slice bounds and page information.
///
/// # Examples
///
/// ## Basic Usage
///
/// ```rust
/// use bubbletea_widgets::paginator::{Model, Type};
///
/// let mut paginator = Model::new()
///     .with_per_page(10)
///     .with_total_items(150); // Creates 15 pages
///
/// assert_eq!(paginator.total_pages, 15);
/// assert!(paginator.on_first_page());
///
/// paginator.next_page();
/// assert_eq!(paginator.page, 1);
/// ```
///
/// ## Different Display Types
///
/// ```rust
/// use bubbletea_widgets::paginator::{Model, Type};
///
/// let mut paginator = Model::new()
///     .with_total_items(50)
///     .with_per_page(10);
///
/// // Arabic mode (default): "1/5"
/// paginator.paginator_type = Type::Arabic;
/// let arabic_view = paginator.view();
///
/// // Dots mode: "● ○ ○ ○ ○"
/// paginator.paginator_type = Type::Dots;
/// let dots_view = paginator.view();
/// ```
///
/// ## Integration with bubbletea-rs
///
/// ```rust
/// use bubbletea_widgets::paginator::Model as Paginator;
/// use bubbletea_rs::{Model, Cmd, Msg};
///
/// struct App {
///     paginator: Paginator,
///     items: Vec<String>,
/// }
///
/// impl Model for App {
///     fn init() -> (Self, Option<Cmd>) {

///             .with_per_page(10)
///             .with_total_items(items.len());
///             
///         (Self { paginator, items }, None)
///     }
///
///     fn update(&mut self, msg: Msg) -> Option<Cmd> {
///         self.paginator.update(&msg);
///         None
///     }
///
///     fn view(&self) -> String {
///         let (start, end) = self.paginator.get_slice_bounds(self.items.len());
///         let page_items: Vec<String> = self.items[start..end].to_vec();
///

///             "Items:\n{}\n\nPage: {}",
