Coding Standards
Determine if at type meets the requirements of SyncReadStream.
Defined in header <boost/beast/core/stream_traits.hpp>
template< class T> using is_sync_read_stream = see-below;
Metafunctions are used to perform compile time checking of template types.
This type will be std::true_type
if T
meets the requirements, else the type will be std::false_type
.
Use with static_assert
:
template<class SyncReadStream> void f(SyncReadStream& stream) { static_assert(is_sync_read_stream<SyncReadStream>::value, "SyncReadStream type requirements not met"); ...
Use with std::enable_if
(SFINAE):
template<class SyncReadStream> typename std::enable_if<is_sync_read_stream<SyncReadStream>::value>::type f(SyncReadStream& stream);
