Crate hjkl_hover 

Renderer-agnostic hover popup state and geometry.

Handles HoverState, anchor/viewport types, position math (with above/below overflow flip), and keyboard-driven scroll. No rendering types are referenced — the TUI adapter lives in hjkl-hover-tui.

Quick start

use hjkl_hover::{HoverAnchor, HoverState, HoverViewport, position};
use std::time::Instant;

let state = HoverState::new("hello world".to_string(), HoverAnchor::new(5, 3));
let vp = HoverViewport::new(80, 24);
let rect = position(&state, vp);
assert!(rect.x + rect.width <= 80);
assert!(rect.y + rect.height <= 24);
