Detailed Description

A single-threaded cooperatively-scheduled runtime for async tasks.

Member Function Documentation

Post()

void pw::async2::Dispatcher::Post ( Task &  task )

inline

Tells the Dispatcher to run Task to completion. This method does not block.

After Post is called, Task::Pend will be invoked once. If Task::Pend does not complete, the Dispatcher will wait until the Task is "awoken", at which point it will call Pend again until the Task completes.

This method is thread-safe and interrupt-safe.

RunPendableUntilStalled()

template<typename Pendable >

Poll< PendOutputOf< Pendable > > pw::async2::Dispatcher::RunPendableUntilStalled ( Pendable &  pendable )

inline

Runs tasks until none are able to make immediate progress, or until pendable completes.

Returns a Poll containing the possible output of pendable.

RunUntilStalled()

Poll pw::async2::Dispatcher::RunUntilStalled ( Task &  task )

inline

Runs tasks until none are able to make immediate progress, or until task completes.

Returns whether task completed.
