Connect condition requirements

A type X meets the ConnectCondition requirements if it satisfies the requirements of Destructible (C++Std [destructible]) and CopyConstructible (C++Std [copyconstructible]), 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 ep denotes a (possibly const) value of some type satisfying the endpoint requirements.

Table 10. ConnectCondition requirements

expression	return type	assertion/note pre/post-condition
`x(ec, ep)`	`bool`	Returns `true` to indicate that the `connect` or `async_connect` algorithm should attempt a connection to the endpoint `ep`. Otherwise, returns `false` to indicate that the algorithm should not attempt connection to the endpoint `ep`, and should instead skip to the next endpoint in the sequence.
