Returns a set of each FiberRef in this collection.
Gets the value of the specified FiberRef in this collection of
FiberRef values if it exists or None otherwise.
Gets the value of the specified FiberRef in this collection of
FiberRef values if it exists or the initial value of the FiberRef
otherwise.
Sets the value of each FiberRef for the fiber running this effect to
the value in this collection of FiberRef values.
FiberRefsis a data type that represents a collection ofFiberRefvalues. This allows safely propagatingFiberRefvalues across fiber boundaries, for example between an asynchronous producer and consumer.
