Types

type t

Error

type error =

| Overflow of string

val error_to_string : error -> string

exception Failure of error

Creator

val create : unit -> t

val clear : t -> unit

Clear the content of the internal buffer(s), but does not release memory

since 2.1

val reset : t -> unit

Clears the content and resets internal storage to its initial memory consumption. This is more costly than clear but can be useful after a very large message was encoded.

since 2.1

Convertion

val to_bytes : t -> bytes

val to_string : t -> string

val write_chunks : (bytes -> int -> int -> unit) -> t -> unit

write_chunks w e calls the write function w (e.g output oc for some output channel oc) on every chunk inside e. The number of chunks is an implementation detail.

since 2.1

Encoding Functions

val key : (int * payload_kind) -> t -> unit

key (k, pk) e writes a key and a payload kind to e.

val nested : (t -> unit) -> t -> unit

nested f e applies f to an encoder for a message nested in e.

val map_entry : 
  encode_key:('a -> t -> unit) ->
  encode_value:('b -> t -> unit) ->
