pub fn window(
source: impl BufRead,
rows: usize,
separator: u8,
comment: Option<&str>,
) -> Result<Vec<Vec<String>>>Expand description
The first rows data lines of source, read on from where its header lines ended,
each split on separator and trimmed: the lines a scan infers its types from. A
line that starts with comment, or is blank, is not one. Stops at
[MAX_WINDOW_BYTES].
