//! Spinner widget for LLM streaming indication.
//!
//! Provides an animated braille spinner using the throbber-widgets-tui crate.
//! The spinner indicates when Claude is actively streaming a response.

use ratatui::layout::Rect;
use ratatui::style::Style;
use ratatui::Frame;
use throbber_widgets_tui::{Throbber, ThrobberState, BRAILLE_SIX};

use crate::tui::theme::colors::CRAIL;

/// Render an animated braille spinner.
///
/// The spinner uses the BRAILLE_SIX pattern (6-dot braille animation)
/// styled with Claude's brand color (Crail).
///
/// # Arguments
///
/// * `frame` - The ratatui Frame to render into
/// * `area` - The rectangular area to render the spinner
/// * `state` - Mutable reference to the spinner state (for animation)
/// * `label` - Text label to display next to the spinner
///
/// # Example
///
/// ```ignore
/// // In your render function:
/// if app.is_streaming {
///     render_spinner(frame, spinner_area, &mut app.spinner_state, "Thinking...");
/// }
/// ```
