The current state of execution of the fiber. This is a continuation, or nil while the fiber is running or completed.

The A_Function that suspended this fiber, or nil if it's not suspended.

The result type of this fiber's type.

A map from atoms to values. Each fiber has its own unique such map, which allows processes to record fiber-specific values. The atom identities ensure modularity and non-interference of these keys.

A map from atoms to heritable values. When a fiber forks a new fiber, the new fiber inherits this map. The atom identities ensure modularity and non-interference of these keys.

The result of having running this fiber to completion. Always nil if the fiber has not yet completed.

Not yet implemented. This will be a function that should be invoked after the fiber executes each nybblecode. Using nil here means run without this special single-stepping mode enabled.

A set of fibers waiting to join the current fiber. That is, these are fibers that are waiting for this fiber to end its execution, in either success or failure.
