The number of receivers associated with the channel.

§destroy: Atomic<bool>
🔬This is a nightly-only experimental API. (mpmc_channel #126840)

Set to true if the last sender or the last receiver reference deallocates the channel.

§chan: C
🔬This is a nightly-only experimental API. (mpmc_channel #126840)
