[section:Handler Handlers]
A handler must satisfy the requirements of `Destructible` (C++Std
[destructible]) and `MoveConstructible` (C++Std [moveconstructible]).
A handler may expose additional information and behaviour via [link
asio.overview.model.associators associators], such as [link
asio.reference.associated_allocator `associated_allocator`], [link
asio.reference.associated_executor `associated_executor`], and [link
asio.reference.associated_cancellation_slot `associated_cancellation_slot`].
