FiffInfo is the C++ counterpart of MNE-Python's mne.Info dictionary. It collects everything stored under FIFFB_MEAS / FIFFB_MEAS_INFO of a FIFF file: per-channel descriptors (FiffChInfo via FiffInfoBase), sampling frequency, lowpass / highpass filter cutoffs, line frequency, measurement date, subject info, experimenter, projector list (FiffProj), CTF software compensation list (FiffCtfComp), HPI fit results, the device→head and CTF compensation transforms, the FIFFB_ISOTRAK digitization (FiffDigPoint), and the per-channel calibration vectors.

Every higher-level container in FIFFLIB (FiffRawData, FiffEvoked, FiffCov, FiffEvokedSet) carries a FiffInfo so that downstream consumers (filtering, source localization, plotting, BIDS export) can interpret the data without re-reading the file.
