Buffers backed by byte sequences that grow automatically. Support insertion and deletion at any position within the buffer. Include some support for UTF-8 encoding.

type t = {
  1. mutable buf : Stdlib.Bytes.t;
  2. mutable len : int;
}
val ensure : t -> int -> unit
val create : unit -> t

Create an empty buffer.

val copy : t -> t

Creates a copy of a buffer.

val contents : t -> string

Buffer contents, as a string.

val byte_length : t -> int

Buffer size in bytes.

val uchar_length : t -> int

Buffer size in utf-8 chars.

val index_of_uchar : t -> int -> int

Byte index of the nb-th utf-8 char.

val nth : t -> int -> char

Get the byte at the specified byte index.

val sub : t -> int -> int -> string

Get the substring from the specified byte index.

val add_char : t -> char -> unit

Append a byte at the end of the buffer.

val add_substring : t -> string -> int -> int -> unit

Append a part of a string at the end of the buffer.

val add_string : t -> string -> unit

Append a string at the end of the buffer.

val insert_char : t -> int -> char -> unit

Insert a byte at the specified byte index.

val insert_substring : t -> int -> string -> int -> int -> unit

Insert a substring at the specified byte index.

val insert_string : t -> int -> string -> unit

Insert a string at the specified byte index.

val delete : t -> int -> int -> unit

Delete some bytes at the specified byte index.

val clear : t -> unit

Reset the buffer to 0 length.

val output : Stdlib.out_channel -> t -> unit

Print to buffer.
