cljs-async.cljs.core
Promises and futures largely compatible with the clojure.core api.
The main difference is, that [[cljs.core/deref]]/@ cannot be used
on promises and futures. Instead async-deref can be used to work
with the respective results asynchronously. Also, futures may do
asynchronous operations, by returning a core/promise.
Note that [[cljs.core/realized?]] works on both promises and futures.

async-derefcljs
(async-deref v)(async-deref v timeout-ms timeout-val)Returns a js/Promise of the result of the given promise or future, optionally with a timeout.
Returns a js/Promise of the result of the given promise or future, optionally with a timeout.
delivercljs
(deliver p v)Delivers the supplied value to the promise, releasing any pending derefs. A subsequent call to deliver on a promise will have no effect.
Delivers the supplied value to the promise, releasing any pending derefs. A subsequent call to deliver on a promise will have no effect.
futurecljmacro
(future & body)Takes a body of expressions and yields a future object that will
evaluate the body later, and will cache the result and return it on
all subsequent calls to async-deref.
Takes a body of expressions and yields a future object that will evaluate the body later, and will cache the result and return it on all subsequent calls to [[async-deref]].
future-callcljs
(future-call thunk)Takes a function of no args and yields a future object that will
invoke the function later, and will cache the result and return it on
all subsequent calls to async-deref.
Takes a function of no args and yields a future object that will invoke the function later, and will cache the result and return it on all subsequent calls to [[async-deref]].
future-cancelcljs
(future-cancel f)Cancels the future, if possible.
Cancels the future, if possible.
future-cancelled?cljs
(future-cancelled? f)Returns true if the given future is cancelled.
Returns true if the given future is cancelled.
future-done?cljs
(future-done? f)Returns true if the given future is done.
Returns true if the given future is done.
future?cljs
(future? v)Returns true if v is a future.
Returns true if `v` is a future.
IAsyncDerefcljsprotocol
-async-derefcljs
(-async-deref this)Returns a js/Promise resolving to the value of this once it is available.
Returns a js/Promise resolving to the value of this once it is available.
IAsyncDerefWithTimeoutcljsprotocol
-async-deref-with-timeoutcljs
(-async-deref-with-timeout this msec timeout-val)Returns a js/Promise resolving to the value of this once it is available, or to the given value after a timeout of the given number of milliseconds.
Returns a js/Promise resolving to the value of this once it is available, or to the given value after a timeout of the given number of milliseconds.
promisecljs
(promise)Returns a promise object that can be read with async-deref, and set,
once only, with deliver.
Returns a promise object that can be read with [[async-deref]], and set, once only, with [[deliver]].
