Abstraction of the transformation source module.
A source that can accept input step by step, and can close input explicitly.
size_t write(span< const uint8_t > buf)
Accept input data and directly write input into next transformation module.
void end()
Close the input interface and directly notify the next module the end of input.
There are three types of module in a transformation chain: Source, Transform, and Sink.
