AByteBufferView
Acts like std::string_view but for AByteBuffer.
Definition AByteBufferView.h:24

IInputStream
Represents an input stream.
Definition IInputStream.h:26

IInputStream::read
virtual size_t read(char *dst, size_t size)=0
Reads up to size bytes from stream. Blocking (waiting for new data) is allowed.
