Struct FrameUniforms 

pub struct FrameUniforms { /* private fields */ }

Per-frame uniform payloads — a typed map of engawa ResourceId → bytemuck-encoded bytes that WgpuDispatcher::dispatch_with writes into the corresponding BoundResource::Uniform buffers before any pass of that dispatch is encoded, so every node in the graph walk sees the same frame data.

Entries are inserted through the typed FrameUniforms::set / FrameUniforms::with surface (bytemuck::Pod values only) — there is no raw-bytes ingress, so a non-Pod or padding-carrying struct cannot enter the map (compile error at the bound, not a runtime check).

Implementations

impl FrameUniforms

pub fn new() -> Self

pub fn with<P: Pod>(self, id: impl Into<ResourceId>, params: &P) -> Self

Builder-style insert of one Pod params value.

pub fn set<P: Pod>(&mut self, id: impl Into<ResourceId>, params: &P)

Insert (or replace) one Pod params value.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = (&ResourceId, &[u8])>

Iterate entries in deterministic (BTreeMap) order.
