val make_raw : ?headers:Headers.t -> code:Response_code.t -> string -> t

Make a response from its raw components, with a string body. Use "" to not send a body at all.

val make_raw_stream : 
  ?headers:Headers.t ->
  code:Response_code.t ->
  byte_stream ->
  t

Same as make_raw but with a stream body. The body will be sent with the chunked transfer-encoding.

val make : 
  ?headers:Headers.t ->
  (body, Response_code.t * string) Stdlib.result ->
  t

make r turns a result into a response.

make (Ok body) replies with 200 and the body.
make (Error (code,msg)) replies with the given error code and message as body.

val make_string : 
  ?headers:Headers.t ->
  (string, Response_code.t * string) Stdlib.result ->
  t

Same as make but with a string body.

val make_stream : 
  ?headers:Headers.t ->
  (byte_stream, Response_code.t * string) Stdlib.result ->
  t

Same as make but with a stream body.

val fail : 
  ?headers:Headers.t ->
  code:int ->
  ('a, unit, string, t) Stdlib.format4 ->
  'a

Make the current request fail with the given code and message. Example: fail ~code:404 "oh noes, %s not found" "waldo".

val fail_raise : code:int -> ('a, unit, string, 'b) Stdlib.format4 -> 'a

Similar to fail but raises an exception that exits the current handler. This should not be used outside of a (path) handler. Example: fail_raise ~code:404 "oh noes, %s not found" "waldo"; never_executed()

val pp : Stdlib.Format.formatter -> t -> unit

Pretty print the response.
