Function ZL_Compressor_registerPipeEncoder 

pub unsafe extern "C" fn ZL_Compressor_registerPipeEncoder(
    cgraph: *mut ZL_Compressor,
    ctd: *const ZL_PipeEncoderDesc,
) -> ZL_NodeID

Register a custom pipe encoder, to be employed in upcoming Graph. This registration is specialized for simple pipe transforms. Counterpart: ZL_DCtx_registerPipeDecoder(). This action creates a NodeID, provided as @return value. Graphs using custom encoders are only decodable if, at decompression time, a custom decoder of same CTid is registered.
