Trait used for testing whether a type satisfies the requirements of a disposition.
template< typename T> struct is_disposition : public integral_constant< bool, automatically_determined >
To be a valid disposition, a type must be nothrow default-constructible,
nothrow move-constructible, nothrow move-assignable, and there must be a
specialisation of the disposition_traits
template for
the type that provides the following static member functions: * not_an_error:
Takes an argument of type const T&
and returns a bool
.
throw_exception:
Takes an argument of type T
.
The caller of this function must not pass a disposition value for which
not_an_error
returns
true. This function must not return.
to_exception_ptr:
Takes an argument of type T
and returns a value of type std::exception_ptr
.
