Struct GeometryHandle 

pub struct GeometryHandle<T> { /* private fields */ }

An app-owned, versioned handle to one batch of geometry.

Cheap to clone (Arc bump). See the module docs for the upload/caching contract. Type aliases MeshHandle, PointsHandle, and LinesHandle name the concrete instantiations used by the marks.

Implementations

impl<T: GeometryData> GeometryHandle<T>

pub fn new(data: T) -> Self

Create a handle, allocating a fresh GeometryId and computing bounds. Revision starts at 1.

pub fn set(&self, data: T)

Replace the geometry and advance the revision, recomputing bounds. The backend re-uploads on its next draw because the revision moved.

This is the baseline update path: it re-uploads the whole buffer. Finer-grained update_range / append paths are designed to slot in later (the handle is the stable surface) without breaking callers of set.

pub fn id(&self) -> GeometryId

Stable identity for backend buffer caches.

pub fn revision(&self) -> u64

Monotonic revision; advances on every GeometryHandle::set.

pub fn bounds(&self) -> Aabb

Cached bounds of the current geometry.

pub fn snapshot(&self) -> (Arc<T>, u64)

Snapshot the current data and revision for upload. Returns an Arc clone (no geometry copy) plus the revision it corresponds to, so the backend can cache by (id, revision).
