pub const MAX_KEYMATCH_LIST: usize = 512;Expand description
How many elements of a list-valued KeyMatch field are considered.
A KeyMatch field holding a Value::List acts as a set of foreign keys:
each string element that names a live destination node yields its own edge.
Only the first MAX_KEYMATCH_LIST elements in stored order participate —
in matching, in the src-side index, and in candidate lookup — so one node
can never fan out without bound. Elements past the cap are ignored
deterministically: the same list always produces the same edges.
