Expand description

Extra fields for a Block<T>.

Fields§

§start_index: usize

The start index of this block.

Slots in this block have indices in start_index .. start_index + BLOCK_CAP.

§next: AtomicPtr<Block<T>>

The next block in the linked list.

§ready_slots: AtomicUsize

Bitfield tracking slots that are ready to have their values consumed.

§observed_tail_position: UnsafeCell<usize>

The observed tail_position value after the block has been passed by block_tail.
