-| [:bulb:](#3.17 "3.17 explained") | *The intent of this rule is to establish that the Subscriber can request an unbounded number of elements, in any increment above 0 [see [3.9](#3.9)], in any number of invocations of `request`. As it is not feasibly reachable with current or foreseen hardware within a reasonable amount of time (1 element per nanosecond would take 292 years) to fulfill a demand of 2^63-1, it is allowed for a Publisher to stop tracking demand beyond this point. Note, calculations with full precision are limited to 2^53-1 (`Number.MAX_SAFE_INTEGER`) for the `Number` type. Handling values larger than 2^53-1 with full precision requires using an [arbitrary precision arithmetic library](https://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic). |

 A `Subscription` is shared by exactly one `Publisher` and one `Subscriber` for the purpose of mediating the data exchange between this pair. This is the reason why the `subscribe()` method does not return the created `Subscription`, but instead returns `void`; the `Subscription` is only passed to the `Subscriber` via the `onSubscribe` callback.
