Struct DisplayMirror 

pub struct DisplayMirror {
    pub slots: Vec<Option<MirrorPoint>>,
}

Viewer-side slot table: applies DisplayDeltas the way a GPU-buffer viewer does (writes at index = id).

Fields

slots: Vec<Option<MirrorPoint>>

Slots by id (None = free).

Implementations

impl DisplayMirror

pub fn new() -> Self

Empty table.

pub fn apply(&mut self, d: &DisplayDelta) -> Result<(), String>

Applies one delta (removes, then adds, then moves). Returns an error for an inconsistent delta (add into a live slot, move/remove of an empty one); the table may be partially updated then.

pub fn len(&self) -> usize

Number of live points.

pub fn is_empty(&self) -> bool

Whether no point is live.

pub fn points(&self) -> impl Iterator<Item = (u32, &MirrorPoint)> + '_

Live points as (id, point).
