Lwt IO implementation that uses strings to marshal and unmarshal HTTP
IO interface that uses Cohttp.Private.String_io.buf for input data and queues output data into a Buffer.t. Never actually blocks despite the Lwt use, although a future revision may yield when parsing large strings.
include Cohttp.S.IO
with type 'a t = 'a Lwt.t
and type ic = Cohttp.Private.String_io.buf
and type oc = Buffer.t
type 'a t = 'a Lwt.t'a t represents a blocking monad state
a >>= b will pass the result of a to the b function. This is a monadic bind.
val return : 'a -> 'a treturn a will construct a constant IO value.
type ic = Cohttp.Private.String_io.bufic represents an input channel
type oc = Buffer.toc represents an output channel
val with_input_buffer :
ic ->
f:(string -> pos:int -> len:int -> 'a * int) ->
'aread_line ic will read a single line terminated by CR or CRLF from the input channel ic. It returns None if EOF or other error condition is reached.
read ic len will block until a maximum of len characters are read from the input channel ic. It returns an empty string if EOF or some other error condition occurs on the input channel, and can also return fewer than len characters if input buffering is not sufficient to satisfy the request.
write oc s will block until the complete s string is written to the output channel oc.
