Module kotlinx-coroutines-core

Core primitives to work with coroutines.

Package kotlinx.coroutines.experimental

General-purpose coroutine builders and contexts.

launch(context) {...} to start a coroutine in the given context and get reference to its Job.
run(context) {...} to switch to a different context inside a coroutine.
runBlocking {...} to use asynchronous Kotlin APIs from a thread-blocking code.
async(context) {...} to get a deferred result of coroutine execution in a non-blocking way via a light-weight future interface called Deferred.
delay(...) for a non-blocking sleep in coroutines and yield() to release a thread in single-threaded dispatchers.
withTimeout(timeout) {...} scope function to easily set coroutine time-limit (deadline), and NonCancellable context to avoid it when needed.
CommonPool and Unconfined contexts, access to context of a parent coroutine in its CoroutineScope.
newSingleThreadContext(...) and newFixedThreadPoolContext(...) functions, Executor.toCoroutineDispatcher() extension.
Cancellation support with Job interface and suspendCancellableCoroutine helper function.
Debugging facilities for coroutines (run JVM with -ea or -Dkotlinx.coroutines.debug options) and newCoroutineContext(context) function to write user-defined coroutine builders that work with these debugging facilities.

Channels -- non-blocking primitives for communicating a stream of values between coroutines.
