Installation ------------ [](#installation) - add `hhvm/asio-utilities` to your composer.json ResultOrExceptionWrapper ------------------------ [](#resultorexceptionwrapper) When awaiting multiple handles, it can be useful to isolate exceptions from each; ResultOrExceptionWrapper provides this: ``` // HH\Asio\wrap(T): Awaitable $w = await wrap(some_async_function_that_may_throw()); if ($w->isSucceeded()) { $result = $w->getResult(); ... } else { $exception = $w->getException(); ... } ``` Mapping and Filtering Functions ------------------------------- [](#mapping-and-filtering-functions) HHVM 3.6 and above include HH\\Asio\\v() and HH\\Asio\\m() to make it easy to wait on multiple wait handles; it's fairly common to want to combine this with another option, such as mapping or filtering with an async function. These functions are named according to their attributes: First, how they take and return arguments according to types: - v - Vector - m - Map Then, either one or two letters to indicate the operation: - f - filter - fk - filter with key - m - map - mk - map with keys Finally, there is optionally a trailing 'w' to indicate that you want a result or exception wrapper. For 'fw' functions, the behavior is that: - if the filter function returns true, the wrapped element is returned - if the filter function returns false, the element is omitted - if the filter function throws an exception, the wrapped exception is returned This is also available without a filter or mapping operation - vw() and mw(). Function List ------------- [](#function-list) All functions are in the HH\\Asio namespace; `v()` and `m()` are built in to HHVM 3.6 and newer.
