type t

type error = [

| `Malformed_response of string
| `Invalid_response_body_length of Response.t
| `Exn of exn

]

type response_handler = Response.t -> Body.Reader.t -> unit

type error_handler = error -> unit

val request : 
  ?config:Config.t ->
  Request.t ->
  error_handler:error_handler ->
  response_handler:response_handler ->
  Body.Writer.t * t

val next_read_operation : t -> [ `Read | `Close ]

next_read_operation t returns a value describing the next operation that the caller should conduct on behalf of the connection.

val read : t -> Bigstringaf.t -> off:int -> len:int -> int

read t bigstring ~off ~len reads bytes of input from the provided range of bigstring and returns the number of bytes consumed by the connection. read should be called after next_read_operation returns a `Read value and additional input is available for the connection to consume.

val read_eof : t -> Bigstringaf.t -> off:int -> len:int -> int

read_eof t bigstring ~off ~len reads bytes of input from the provided range of bigstring and returns the number of bytes consumed by the connection. read_eof should be called after next_read_operation returns a `Read and an EOF has been received from the communication channel. The connection will attempt to consume any buffered input and then shutdown the HTTP parser for the connection.

val next_write_operation : 
  t ->
  [ `Write of Bigstringaf.t IOVec.t list | `Yield | `Close of int ]

next_write_operation t returns a value describing the next operation that the caller should conduct on behalf of the connection.

val report_write_result : t -> [ `Ok of int | `Closed ] -> unit

report_write_result t result reports the result of the latest write attempt to the connection. report_write_result should be called after a call to next_write_operation that returns a `Write buffer value.

`Ok n indicates that the caller successfully wrote n bytes of output from the buffer that the caller was provided by next_write_operation.
`Closed indicates that the output destination will no longer accept bytes from the write processor.

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

yield_writer t continue registers with the connection to call continue when writing should resume. yield_writer should be called after next_write_operation returns a `Yield value.

val report_exn : t -> exn -> unit

report_exn t exn reports that an error exn has been caught and that it has been attributed to t. Calling this function will switch t into an error state. Depending on the state t is transitioning from, it may call its error handler before terminating the connection.

val is_closed : t -> bool
