Byte sequence operations.
Since 4.02.0
val length : bytes -> int
Return the length (number of bytes) of the argument.
val get : bytes -> int -> char
get s n returns the byte at index n in argument s .
Raise Invalid_argument if n not a valid index in s .
val set : bytes -> int -> char -> unit
set s n c modifies s in place, replacing the byte at index n with c .
Raise Invalid_argument if n is not a valid index in s .
val create : int -> bytes
create n returns a new byte sequence of length n . The sequence is uninitialized and
contains arbitrary bytes.
Raise Invalid_argument if n < 0 or n > Sys.max_string_length .
val make : int -> char -> bytes
make n c returns a new byte sequence of length n , filled with the byte c .
Raise Invalid_argument if n < 0 or n > Sys.max_string_length .
val init : int -> f:(int -> char) -> bytes
init n f returns a fresh byte sequence of length n , with character i initialized to the
result of f i .
Raise Invalid_argument if n < 0 or n > Sys.max_string_length .
val empty : bytes
A byte sequence of size 0.
val copy : bytes -> bytes
Return a new byte sequence that contains the same bytes as the argument.
val of_string : string -> bytes
Return a new byte sequence that contains the same bytes as the given string.
val to_string : bytes -> string
Return a new string that contains the same bytes as the given byte sequence.
val sub : bytes -> pos:int -> len:int -> bytes
sub s start len returns a new byte sequence of length len , containing the subsequence of
s that starts at position start and has length len .
Raise Invalid_argument if start and len do not designate a valid range of s .
val sub_string : bytes -> int -> int -> string
Same as sub but return a string instead of a byte sequence.
val fill : bytes -> pos:int -> len:int -> char -> unit
fill s start len c modifies s in place, replacing len characters with c , starting at
start .
Raise Invalid_argument if start and len do not designate a valid range of s .
val blit : src:bytes -> src_pos:int -> dst:bytes -> dst_pos:int -> len:int -> unit
blit src srcoff dst dstoff len copies len bytes from sequence src , starting at index
srcoff , to sequence dst , starting at index dstoff . It works correctly even if src and
dst are the same byte sequence, and the source and destination intervals overlap.
Raise Invalid_argument if srcoff and len do not designate a valid range of src , or if
dstoff and len do not designate a valid range of dst .
val concat : sep:bytes -> bytes list -> bytes
concat sep sl concatenates the list of byte sequences sl , inserting the separator byte
sequence sep between each, and returns the result as a new byte sequence.
val iter : f:(char -> unit) -> bytes -> unit
iter f s applies function f in turn to all the bytes of s . It is equivalent to f (get s
0); f (get s 1); ...; f (get s (length s - 1)); () .
val iteri : f:(int -> char -> unit) -> bytes -> unit
Same as Bytes.iter , but the function is applied to the index of the byte as first
argument and the byte itself as second argument.
val map : f:(char -> char) -> bytes -> bytes
map f s applies function f in turn to all the bytes of s and stores the resulting bytes in
a new sequence that is returned as the result.
val mapi : f:(int -> char -> char) -> bytes -> bytes
mapi f s calls f with each character of s and its index (in increasing index order) and
stores the resulting bytes in a new sequence that is returned as the result.
val trim : bytes -> bytes
Return a copy of the argument, without leading and trailing whitespace. The bytes regarded
as whitespace are the ASCII characters ' ' , '\012' , '\n' , '\r' , and '\t' .
val escaped : bytes -> bytes
Return a copy of the argument, with special characters represented by escape sequences,
following the lexical conventions of OCaml.
val index : bytes -> char -> int
index s c returns the index of the first occurrence of byte c in s .
Raise Not_found if c does not occur in s .
val rindex : bytes -> char -> int
rindex s c returns the index of the last occurrence of byte c in s .
Raise Not_found if c does not occur in s .
val index_from : bytes -> int -> char -> int
index_from s i c returns the index of the first occurrence of byte c in s after position i
. Bytes.index s c is equivalent to Bytes.index_from s 0 c .
Raise Invalid_argument if i is not a valid position in s . Raise Not_found if c does not
occur in s after position i .
val rindex_from : bytes -> int -> char -> int
rindex_from s i c returns the index of the last occurrence of byte c in s before position
i+1 . rindex s c is equivalent to rindex_from s (Bytes.length s - 1) c .
Raise Invalid_argument if i+1 is not a valid position in s . Raise Not_found if c does
not occur in s before position i+1 .
val contains : bytes -> char -> bool
contains s c tests if byte c appears in s .
val contains_from : bytes -> int -> char -> bool
contains_from s start c tests if byte c appears in s after position start . contains s c
is equivalent to contains_from s 0 c .
Raise Invalid_argument if start is not a valid position in s .
val rcontains_from : bytes -> int -> char -> bool
rcontains_from s stop c tests if byte c appears in s before position stop+1 .
Raise Invalid_argument if stop < 0 or stop+1 is not a valid position in s .
val uppercase : bytes -> bytes
Return a copy of the argument, with all lowercase letters translated to uppercase,
including accented letters of the ISO Latin-1 (8859-1) character set.
val lowercase : bytes -> bytes
Return a copy of the argument, with all uppercase letters translated to lowercase,
including accented letters of the ISO Latin-1 (8859-1) character set.
val capitalize : bytes -> bytes
Return a copy of the argument, with the first byte set to uppercase.
val uncapitalize : bytes -> bytes
Return a copy of the argument, with the first byte set to lowercase.
type t = bytes
An alias for the type of byte sequences.
val compare : t -> t -> int
The comparison function for byte sequences, with the same specification as
Pervasives.compare . Along with the type t , this function compare allows the module
Bytes to be passed as argument to the functors Set.Make and Map.Make .
