Class type

Byte buffer.

A dynamic vector of bytes.

  • since 3.7
type t
type 'a iter = ('a -> unit) -> unit
val create : ?cap:int -> unit -> t

Create a new buffer with given initial capacity.

val length : t -> int

Current length.

val is_empty : t -> bool

is_empty b is length b=0

val capacity : t -> int

Current capacity (size of the array returned by bytes)

val bytes : t -> bytes

Access the underlying byte buffer. This buffer can change after operations that affect the capacity (e.g. add_char).

val clear : t -> unit
val ensure_cap : t -> int -> unit

ensure_cap self n ensures that capacity self >= n.

val shrink_to : t -> int -> unit

shrink_to buf n reduces length buf to at most n. Does nothing if the length is already <= n.

val add_char : t -> char -> unit

Push a character at the end.

val append_bytes : t -> bytes -> unit
val append_subbytes : t -> bytes -> int -> int -> unit
val append_string : t -> string -> unit
val append_substring : t -> string -> int -> int -> unit
val append_buf : t -> Buffer.t -> unit
val append_iter : t -> char iter -> unit
val append_seq : t -> char Seq.t -> unit
val get : t -> int -> char
val unsafe_get : t -> int -> char
val set : t -> int -> char -> unit
val unsafe_set : t -> int -> char -> unit
val contents : t -> string

Copy the internal data to a string

val contents_bytes : t -> bytes

Copy the internal data to a byte buffer

val iter : (char -> unit) -> t -> unit
val fold_left : ('a -> char -> 'a) -> 'a -> t -> 'a
val of_iter : char iter -> t
val of_seq : char Seq.t -> t
val to_iter : t -> char iter
val to_seq : t -> char Seq.t
