Queue

A queue, useful for coordinating producer and consumer coroutines.

If $(D_PSYMBOL maxSize) is equal to zero, the queue size is infinite. Otherwise $(D_PSYMBOL put()) will block when the queue reaches maxsize, until an item is removed by $(D_PSYMBOL get()).

You can reliably know this $(D_PSYMBOL Queue)'s size with $(D_PSYMBOL qsize()), since your single-threaded asynchronous application won't be interrupted between calling $(D_PSYMBOL qsize()) and doing an operation on the Queue.

This class is not thread safe.

class Queue (

size_t maxSize = 0

) {

this(EventLoop eventLoop);

string toString();

T get_();

void put_(T item);

bool empty [@property getter];

bool full [@property getter];

void putNowait(T item);

size_t qsize [@property getter];

void taskDone();

size_t maxsize [@property getter];

}
