-----------------------------------------------------------------
e.g.
{code}
// sufficiently large
char buffer[4096];
boost::shared_ptr<TMemoryBuffer> transport{ new TMemoryBuffer(buffer, 1024,
TMemoryBuffer::OBSERVE) };
boost::shared_ptr<TBinaryProtocol> protocol{ new TBinaryProtocol(transport)
};
object.write(protocol.get());
{code}
We will get
{code}
terminate called after throwing an instance of
'apache::thrift::transport::TTransportException'
what(): Insufficient space in external MemoryBuffer
Aborted (core dumped)
{code}

> It would be great if there is a transport class which 1. does not need to
> care about the memory management, 2. is capable of both read and write
> operations.
> TMemoryBuffer is very close to the requirements, but no data can be written
> to observed TMemoryBuffer as stated in the comments.
