is_sync_write_stream

Determine if T meets the requirements of SyncWriteStream.

Synopsis

Defined in header <boost/beast/core/stream_traits.hpp>

template<
    class T>
using is_sync_write_stream = see-below;
Description

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.

Example

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);
