Here be dragons. You may wish to use these functions over the bracketed interface above, but you MUST wait on Pipe.upstream_flushed after closing the pipe.

Escape the a CSV field if need be.

val escape_field : ?quote:char -> string -> string

Escape a CSV (even if doesn't have any characters that require escaping).

Get the escaped length of one quoted field (without the quotes). Returns None if the field doesn't need to be escaped.

  dst_pos:int ->
  len:int ->
  int

Copy and escapes the content of a field over from one string to another. This does not put the quotes in.

val of_writer : 
  ?sep:char ->
  ?line_breaks:[ `Unix | `Windows ] ->

  'a Write.t ->
  Async.Writer.t ->
  'a Async.Pipe.Writer.t

Make a pipe writer for 'as from a writer. The 'as will be written out as CSVs.
