pub fn read_header(path: &Path) -> Result<(usize, usize, usize)>Expand description
Parse only the format header of path, returning (byte_offset, n, dim):
where the f32 payload begins and its shape. The payload itself is not
read, so a large dataset is not pulled into the heap.
ยงErrors
Returns an error if the extension is unknown or the header does not parse.
