If strip is true (default is false) then spaces will be stripped from the beginning and end of fields.
If
skip_lines
is given then that number of lines will be read and discarded from the top of the file or Reader.t given.If
on_parse_error
is `Raise any lines that fail to parse will raise an exception. If `Handle is given the offending line will be passed to the function given, which may then indicate that processing should continue or finish.
val buffer_size : int
Recommendation based on the largest reads and writes observed off a disk or socket.
