[#leaf]
== cobalt/leaf.hpp

Async provides integration with boost.leaf.
It provides functions similar to leaf that take an <<awaitable, awaitables>>
instead of a function object and return an <<awaitable, awaitable>>.

template<awaitable TryAwaitable, typename ... H >
auto try_catch(TryAwaitable && try_coro, H && ... h );

template<awaitable TryAwaitable, typename ... H >
auto try_handle_all(TryAwaitable && try_coro, H && ... h );

template<awaitable TryAwaitable, typename ... H >
auto try_handle_some(TryAwaitable && try_coro, H && ... h );
