Struct ActivePlusAdjacent 

pub struct ActivePlusAdjacent { /* private fields */ }

Tick the active screen’s declared neighbors at full rate while all other inactive screens use a reduced divisor.

Use when navigation between adjacent screens is common (e.g. tab bars) and you want instant-feeling switches without a learned model.

Implementations

impl ActivePlusAdjacent

pub fn new(background_divisor: u64) -> Self

Create an empty adjacency strategy with the given background divisor.

A divisor of 0 is clamped to 1.

pub fn add_adjacency(&mut self, screen: &str, neighbors: &[&str])

Declare that screen is adjacent to the given neighbors.

pub fn from_tab_order(screens: &[&str], background_divisor: u64) -> Self

Build adjacency from a linear tab order.

Each screen becomes adjacent to its immediate left and right neighbors (edges only have one neighbor).

from_tab_order(["A", "B", "C"], 10)
// A <-> B, B <-> C

pub const fn background_divisor(&self) -> u64

Return the background divisor.

pub fn adjacency(&self) -> &HashMap<String, Vec<String>>

Return a reference to the adjacency map.
