Detailed Description

Minimal RFC-4180-ish CSV parser: comma-delimited, double-quote-quoted fields, "" as an escaped quote,
or \r
line endings. Whole file loaded into memory at once – no streaming/chunked reading in this phase, matching MnistIdxLoader's own whole-file-at-once precedent.

Note

Chosen over fetching Arrow C++ (campaign_exai_dl_library_data_pipeline Decision Point 1): Arrow's columnar/zero-copy value proposition doesn't apply to this row-oriented, float32-only, small-scale use case, and would break this project's minimal-FetchContent discipline (GoogleTest + optional pybind11 only, today).

Member Function Documentation

Load()

static CsvTable pulsatrix::CsvReader::Load ( const std::string &  path, bool  has_header = true  )

static

Parameters

path	Path to the CSV file.
has_header	Whether row 0 is a header (excluded from CsvTable::rows, stored in CsvTable::header instead).

Returns

The parsed table.

Exceptions

std::runtime_error

if the file can't be opened, a quoted field is never closed, has_header is true but the file has no rows at all, or any data row's field count doesn't match the header's (or, with no header, the first row's) field count – external boundary: malformed file content, not an internal invariant.
