pub fn state_root(state: &State) -> CapHashExpand description
State-root: SSZ hash_tree_root of the cache’s blobs.
Each leaf is a StateLeaf { blob_hash, cap_hash } container. The
full state root is hash_tree_root of the Vec<StateLeaf>, which
merkleizes the per-leaf roots, pads to the next power of two, and
mixes in the length per SSZ List semantics.
Leaves are sorted by blob_hash explicitly so the result is
independent of insertion order (the cap store is a HashMap, whose
iteration order is unspecified). Empty caches reduce to the SSZ
canonical empty-list root.
