Module IO.WriteContext
val create :
write:('a -> buf:string -> pos:int -> len:int -> int) ->
compression:Capnp.Codecs.compression_t ->
'a ->
'a t
create ~write ~compression descr
creates a new context for writing data to the specified descriptor. compression
specifies the compression format, if any.
The semantics of the write
function shall mimic that of Unix.single_write
, attempting to write a substring from the buf
and returning the number of bytes actually written.
val enqueue_message : 'a t -> 'cap Capnp.Message.BytesMessage.Message.t -> unit
enqueue_message context message
places the message
in the outgoing queue of the write context
. No data will be written to the underlying descriptor.
val bytes_remaining : 'a t -> int
bytes_remaining context
obtains the number of unwritten bytes currently stored in the write context
.
val write : 'a t -> int
write context
attempts to write some of the queued data to the underlying descriptor associated with the write context
.
val write_message : 'a t -> 'cap Capnp.Message.BytesMessage.Message.t -> unit
write_message context message
places the message
in the outgoing queue of the write context
, then invokes write
in a loop until all queued data has been written.
