module File_writer

: sig

File_writer is a thin wrapper around Writer with a couple of extra features:

It keeps track of all the file writers that have been created so that it can iterate over them to find out how many bytes in total they have to write.
It keeps track of whether the underlying writer has failed, and if so silently ignores future operations. This can prevent pointlessly filling up a writer's buffer with data that will never go anywhere.

type t

val create : ?append:bool -> string -> t Import.Deferred.t

create file opens file, creating it if it doesn't exist.

val write : t -> string -> unit

write t s writes s to the file.

val write_substring : t -> Core.Std.Substring.t -> unit

val write_bigsubstring : t -> Core.Std.Bigsubstring.t -> unit

val schedule_bigstring : t -> Core.Std.Bigstring.t -> unit

val write_bin_prot : t -> 'a Core.Std.Bin_prot.Type_class.writer -> 'a -> unit

val write_sexp : ?hum:bool -> t -> Core.Std.Sexp.t -> unit

val monitor : t -> Import.Monitor.t

val bytes_to_write : unit -> int

bytes_to_write () returns the sum over all async_file_writers of how many bytes they need to write.

val flushed : t -> unit Import.Deferred.t

val close : t -> unit Import.Deferred.t

val sexp_of_t : t -> Sexplib.Sexp.t
