Common (bin_prot.Bin

type pos = int

Position within buffers

type pos_ref = pos Pervasives.ref

Reference to a position within buffers

type buf = (char, Bigarray.int8_unsigned_elt, Bigarray.c_layout) Bigarray.Array1.t

Buffers

val create_buf : int ‑> buf

create_buf n creates a buffer of size n.

val buf_len : buf ‑> int

buf_len buf returns the length of buf.

val assert_pos : pos ‑> unit

assert_pos pos

Raises Invalid_argument: if position pos is negative.

val check_pos : buf ‑> pos ‑> unit

check_pos buf pos

Raises Buffer_short: if position pos exceeds the length of buffer buf.

val check_next : buf ‑> pos ‑> unit

check_next buf pos

Raises Buffer_short: if the next position after pos exceeds the length of buffer buf.

val safe_get_pos : buf ‑> pos_ref ‑> pos

safe_get_pos buf pos_ref

Returns the position referenced by pos_ref within buffer buf.
Raises Buffer_short: if the position exceeds the length of the buffer.

val blit_string_buf : ?src_pos:int ‑> string ‑> ?dst_pos:int ‑> buf ‑> len:int ‑> unit

blit_string_buf ?src_pos src ?dst_pos dst ~len blits len bytes of the source string src starting at position src_pos to buffer dst starting at position dst_pos.

Raises Invalid_argument: if the designated ranges are invalid.

val blit_buf_string : ?src_pos:int ‑> buf ‑> ?dst_pos:int ‑> string ‑> len:int ‑> unit

blit_buf_string ?src_pos src ?dst_pos dst ~len blits len bytes of the source buffer src starting at position src_pos to string dst starting at position dst_pos.

Raises Invalid_argument: if the designated ranges are invalid.

val blit_buf : ?src_pos:int ‑> src:buf ‑> ?dst_pos:int ‑> dst:buf ‑> int ‑> unit

blit_buf ?src_pos ~src ?dst_pos ~dst len blits len bytes of the source buffer src starting at position src_pos to destination buffer dst starting at position dst_pos.

Raises Invalid_argument: if the designated ranges are invalid.

Errors and exceptions

exception Buffer_short

Buffer too short for read/write operation

exception No_variant_match

Used internally for backtracking

module ReadError : sig ... end

exception Read_error of ReadError.t * pos

ReadError (err, err_pos)

exception Poly_rec_write of string

PolyRecWrite type gets raised when the user attempts to write or estimate the size of a value of a type that is bound through a polymorphic record field in type definition type.

exception Empty_type of string

EmptyType gets raised when the user attempts to write or estimate the size of a value of an empty type, which would not make sense.

val raise_read_error : ReadError.t ‑> pos ‑> 'a

raise_read_error err pos

val raise_variant_wrong_type : string ‑> pos ‑> 'a

raise_variant_wrong_type name pos

val raise_concurrent_modification : string ‑> 'a

raise_concurrent_modification loc

Raises Failure: if a binary writer detects a concurrent change to the underlying data structure.

val array_bound_error : unit ‑> 'a

array_bound_error ()

Bigarrays

type vec32 = (float, Bigarray.float32_elt, Bigarray.fortran_layout) Bigarray.Array1.t

type vec64 = (float, Bigarray.float64_elt, Bigarray.fortran_layout) Bigarray.Array1.t

type vec = vec64

type mat32 = (float, Bigarray.float32_elt, Bigarray.fortran_layout) Bigarray.Array2.t

type mat64 = (float, Bigarray.float64_elt, Bigarray.fortran_layout) Bigarray.Array2.t

type mat = mat64

Miscellaneous

val copy_htbl_list : ('a, 'b) Hashtbl.t ‑> ('a * 'b) list ‑> ('a, 'b) Hashtbl.t

copy_htbl_list htbl lst adds all (key, value) pairs in lst to hash table htbl.
