Constant rusty_pool::MAX_SIZE

pub const MAX_SIZE: usize = (1 << (BITS / 2)) - 1; // 0x0000_0000_ffff_ffffusize

The absolute maximum number of workers. This corresponds to the maximum value that can be stored within half the bits of usize, as two counters (total workers and idle workers) are stored in one AtomicUsize.
