HH\Lib\Dict\filter_with_key_async

Meta Engineer?

This is available as Dict\filter_with_key_async in the www repository.

Like filter_async, but lets you utilize the keys of your dict too

namespace HH\Lib\Dict;

function filter_with_key_async<Tk as arraykey, Tv>(
  KeyedContainer<Tk, Tv> $traversable,
  (function(Tk, Tv): Awaitable<bool>) $predicate,
): Awaitable<dict<Tk, Tv>>;

For non-async filters with key, see Dict\filter_with_key().

Time complexity: O(n * p), where p is the complexity of $value_predicate Space complexity: O(n)
