Struct PreCascadeTransfers 

pub struct PreCascadeTransfers {
    pub image_callbacks: Vec<(usize, CoreImageCallback)>,
    pub callbacks: Vec<(usize, CoreCallbackDataVec)>,
    pub datasets: Vec<(usize, RefAny)>,
}

RefAny payloads collected during the fingerprint walk.

Transferred onto the retained DOM when the produce side is skipped. The skip path keeps last frame’s StyledDom, but callbacks/image callbacks must use the freshly-created RefAnys (they may reference new app state) — same transfer regenerate_layout’s equivalence branch has always done, minus the cascade it used to pay to get here. Indices are flattened NodeIds.

Fields

image_callbacks: Vec<(usize, CoreImageCallback)>

(flattened NodeId index, fresh image callback) for every NodeType::Image(DecodedImage::Callback) node.

callbacks: Vec<(usize, CoreCallbackDataVec)>

(flattened NodeId index, fresh event callbacks) for every node with a non-empty callback list.

datasets: Vec<(usize, RefAny)>

(flattened NodeId index, fresh dataset) for every node that carries one. Merged onto the retained DOM by merge_fresh_dataset — the skip path’s equivalent of transfer_states — so a widget’s state survives an identical rebuild and its callbacks (installed from callbacks above) end up on the SAME allocation as its dataset.
