Abstraction of the transformation source module.
A source that can accept input step by step, and can close input explicitly.
Definition: step-source.hpp:46
size_t write(span< const uint8_t > buf)
Accept input data and directly write input into next transformation module.
Definition: step-source.cpp:29
void end()
Close the input interface and directly notify the next module the end of input.
Definition: step-source.cpp:35
size_t write(const uint8_t *buf, size_t size)
Definition: step-source.hpp:64
Definition: data.cpp:25
There are three types of module in a transformation chain: Source, Transform, and Sink.
