Module Async_extended.Csv.Parse_state

At the lowest level, we model csv parsing as a fold over string arrays, one array per row. It is up to you to interpret the header row.

type 'a t

val acc : 'a t ‑> 'a

At any moment, the result of folding over all complete rows seen so far.

val set_acc : 'a t ‑> 'a ‑> 'a t

Can be used to set or clear the current acc

val create : ?strip:bool ‑> ?sep:char ‑> ?quote:[ `No_quoting | `Using of char ] ‑> fields_used:int array option ‑> init:'a ‑> f:(int ‑> 'a ‑> string Fast_queue.t ‑> 'a) ‑> unit ‑> 'a t

val input : 'a t ‑> ?pos:int ‑> ?len:int ‑> string ‑> 'a t

input t ?pos ?len s parses the first len characters of s, starting at position pos. pos defaults to 0 and len defaults to reading up to the end of s.

val finish : 'a t ‑> 'a t

finish t forces an end-of-row. Raises if end-of-row is not permitted here (e.g., within a quoted field). It is permitted to input after a finish.
