Detailed Description

template<size_t MAXQUEUES, class ForwardIterator>
requires std::forward_iterator<ForwardIterator>
struct Ase::QueueMultiplexer< MAXQUEUES, ForwardIterator >

Multiplexer to pop from multiple Queues, while preserving priorities. Order for values at the same priority is unstable. Relies on unqualified calls to `Priority QueueMultiplexer_priority (const ValueType&)`.
