HH\Asio\vmkw

Returns an Awaitable of Vector of ResultOrExceptionWrapper after a mapping operation has been applied to each key/value pair in the provided KeyedTraversable

namespace HH\Asio;

function vmkw<Tk, Tv, Tr>(
  KeyedTraversable<Tk, Tv> $inputs,
  (function(Tk,Tv):Awaitable<Tr>) $callable,
): Awaitable<Vector<HH\Asio\ResultOrExceptionWrapper<Tr>>>;

This function is similar to vmk(), except the Vector in the returned Awaitable contains ResultOrExceptionWrappers instead of raw values.

This function is similar to Vector::mapWithKey(), but the mapping of the key/value pairs are done using Awaitables.

This function is called vmkw because we are returning a vector, doing a mapping operation that includes both keys and values, and each member of the Vector is wrapped by a ResultOrExceptionWrapper.

$callable must return an Awaitable.

The ResultOrExceptionWrappers in the Vector of the returned Awaitable are not available until you await or join the returned Awaitable.
