GenDurable.Context (gen_durable v0.1.6)

The context handed to GenDurable.FSM.step/2 and GenDurable.FSM.handle/2.

state is the FSM's loaded state (a struct when the FSM declares state:, otherwise a plain string-keyed map).

Two signal views: awaited is the subset the step's :await named (what the engine delivers and consumes — empty when the step was not reached via an await), and all is the full instance inbox. Both are empty for handle/2. childs holds this instance's children (spec §11) — populated when a parent wakes from schedule_childs, empty otherwise. See GenDurable.FSM.
