pub type PasteHandler = fn(item: &ClipboardItem, editor: &Entity<Editor>, destination: PasteContext<'_>, cx: &mut App) -> Option<PasteContent>;Expand description
Called once before default clipboard handling. None keeps that behavior.
The entity identifies the editor; do not read or update it during the call.
Use the snapshot and cx.image_store() when calling ImageStore::keep.
