val size_header_length : int
(** [size_header_length] is the standard number of bytes allocated for the size header in
size-prefixed bin-io payloads. This size-prefixed layout is used by the [bin_dump]
and [bin_read_stream] functions below, as well as:
- Core.Std.Bigstring.{read,write}_bin_prot
- Core.Std.Unpack_buffer.unpack_bin_prot
- Async.Std.{Reader,Writer}.{read,write}_bin_prot
among others.
The size prefix is always 8 bytes at present. This is exposed so your program does not
have to know this fact too.
We do not use a variable length header because we want to know how many bytes to read
to get the size without having to peek into the payload. *)
val bin_read_size_header : int Read.reader
val bin_write_size_header : int Write.writer
(** [bin_read_size_header] and [bin_write_size_header] are bin-prot serializers for the
size header described above. *)
val bin_dump : ?header : bool -> 'a writer -> 'a -> buf
(** [bin_dump ?header writer v] uses [writer] to first compute the size of
[v] in the binary protocol, then allocates a buffer of exactly this
size, and then writes out the value. If [header] is [true], the
size of the resulting binary string will be prefixed as a signed
64bit integer.
@return the buffer containing the written out value.
@param header default = [false]
@raise Failure if the size of the value changes during writing,
and any other exceptions that the binary writer in [writer] can raise.
*)
val bin_read_stream :
?max_size : int ->
read : (buf -> pos : int -> len : int -> unit) ->
'a reader -> 'a
(** [bin_read_stream ?max_size ~read reader] reads binary protocol data
from a stream as generated by the [read] function, which places
data of a given length into a given buffer. Requires a header.
The [reader] type class will be used for conversion to OCaml-values.
@param max_size = nothing
@raise Failure if the size of the value disagrees with the one
specified in the header, and any other exceptions that the binary
reader associated with [reader] can raise.
@raise Failure if the size reported in the data header is longer than
[max_size].
