[section:CompletionCondition Completion condition requirements]
A ['completion condition] is a function object that is used with the algorithms
[link asio.reference.read `read`], [link asio.reference.async_read
`async_read`], [link asio.reference.write `write`], and [link
asio.reference.async_write `async_write`] to determine when the algorithm has
completed transferring data.
A type `X` meets the `CompletionCondition` requirements if it satisfies the
requirements of `Destructible` (C++Std [destructible]) and
`MoveConstructible` (C++Std [moveconstructible]), as well as the additional
requirements listed below.
In the table below, `x` denotes a value of type `X`, `ec` denotes a (possibly
const) value of type `error_code`, and `n` denotes a (possibly const) value of
type `size_t`.

Let `n` be the total number of bytes transferred by the read or write
algorithm so far.[br]
[br]
Returns the maximum number of bytes to be transferred on the next
`read_some`, `async_read_some`, `write_some`, or `async_write_some`
operation performed by the algorithm. Returns `0` to indicate that the
algorithm is complete.
