Method try_enqueue

concurrentqueue.h:1076–1080

Enqueues a single item (by copying it). Does not allocate memory. Fails if not enough room to enqueue (or implicit production is disabled because Traits::INITIAL_IMPLICIT_PRODUCER_HASH_SIZE is 0). Note: If using only try_enqueue/try_enqueue_bulk with pre-allocated blocks, configure Traits::IMPLICIT_INITIAL_INDEX_SIZE appropriately to ensure the index has sufficient capacity for the number of block

	// capacity for the number of blocks each producer may need.
	// Thread-safe.
	inline bool try_enqueue(T const& item)
	{
		MOODYCAMEL_CONSTEXPR_IF (INITIAL_IMPLICIT_PRODUCER_HASH_SIZE == 0) return false;
		else return inner_enqueue<CannotAlloc>(item);
	}
	
	// Enqueues a single item (by moving it, if possible).
	// Does not allocate memory (except for one-time implicit producer).
