pub fn store(object: &Object) -> Option<(Key, U64Varint)>Expand description
Build the (Key, Value) pair indexing a Move object by owner.
Returns None for objects that aren’t Move objects (packages,
for example) — those have no StructTag and aren’t part of
this index. For coin-like Move objects the balance is captured
as the ones-complement !balance so richer coins sort first
within their (owner, type) group.
