FIFFLIB::FiffRawData represents a continuous ("raw") Neuromag recording as stored under FIFFB_RAW_DATA / FIFFB_CONTINUOUS_DATA: a FIFFLIB::FiffInfo describing the channels and acquisition setup, a list of FIFFLIB::FiffRawDir entries pointing at each FIFF_DATA_BUFFER tag, the first and last sample indices, the per-channel calibration vector and a FIFFLIB::FiffStream handle for on-demand reads. The FiffStream::read_raw_segment family uses that directory to seek directly to the buffers that cover a requested sample range, decode them through the channel cals and projectors, and return a contiguous Eigen matrix. Drop-in counterpart of mne.io.Raw in MNE-Python.
