Library index

This page is computed from the engine when the docs are written. A function added to yen appears here without a docs edit.

Outside a fleet: (import yen).lib

agent, allowed, asOf, derive, diffData, eval, grant, history, is, jsonSafe, maybe, mkFlake, narrow, opt, stage, validAt, without

Inside a fleet: yen.lib

Modules get the same lib, plus predicates and queries bound to the fleet:

all, cascade, declaredIn, floor, graph, has, holds, labels, nearest, not, same, schema, scopesOf, within
