pub const FUSED_STATE: &str = "$State";Expand description
The accumulator a program with several durable folds is compiled to.
§3.7 fixes “one totally-ordered log per application”, and the runtime holds one accumulator over
it. A program that writes two durable folds has not asked for two logs; it has asked for two
projections of one. crate::split fuses them into a record of this type, which is why the
name is unwritable in the surface syntax: it is a compiler product, and no module publishes it.
