Module `Tezos_p2p.P2p_conn`Source

Type of a connection to a peer, parametrized by the type of messages exchanged as well as meta-information associated to a peer and a connection. It wraps a P2p_socket.t, adding meta-information and data-structures describing a more fine-grained logical state of the connection. It also set up an answering worker that responds to the messages P2p_message.t using the callback functions of a P2p_answerer.t.

Sourceval peer_id : ('msg, 'peer, 'conn) t -> Tezos_base.TzPervasives.P2p_peer.Id.t

Sourceval private_node : ('msg, 'peer, 'conn) t -> bool

private_node t returns 'true' if the node associated to this connection is in private mode

Sourceval trusted_node : ('msg, 'peer, 'conn) t -> bool

trusted_node t returns 'true' if the node associated to this connection is trusted

Sourceval stat : ('msg, 'peer, 'conn) t -> Tezos_base.TzPervasives.P2p_stat.t

stat t is a snapshot of current bandwidth usage for t.

val read : 
  ('msg, 'peer, 'conn) t ->
  'msg Tezos_base.TzPervasives.tzresult Lwt.t

read t returns a message popped from t's app message queue, or fails with Connection_closed.

val is_readable : 
  ('msg, 'peer, 'conn) t ->
  unit Tezos_base.TzPervasives.tzresult Lwt.t

is_readable t returns when there is at least one message ready to be read.

  bool Tezos_base.TzPervasives.tzresult

val write : 
  ('msg, 'peer, 'conn) t ->
  'msg ->
  unit Tezos_base.TzPervasives.tzresult Lwt.t

write t msg is P2p_socket.write t' msg where t' is the internal P2p_socket.t inside t.

val write_sync : 
  ('msg, 'peer, 'conn) t ->
  'msg ->
  unit Tezos_base.TzPervasives.tzresult Lwt.t

write_sync t msg is P2p_socket.write_sync t' msg where t' is the internal P2p_socket.t inside t.

val write_now : 
  ('msg, 'peer, 'conn) t ->
  'msg ->
  bool Tezos_base.TzPervasives.tzresult

write_now t msg is P2p_socket.write_now t' msg where t' is the internal P2p_socket.t inside t.

val encode : 
  ('msg, 'peer, 'conn) t ->
  'msg ->
  'msg P2p_message.t P2p_socket.encoded_message
    Tezos_base.TzPervasives.tzresult

encode t messsage encodes a message to be used with write_encoded_now. It is particularly useful to avoid encoding several times the same message.

val write_encoded_now : 
  ('msg, 'peer, 'conn) t ->
  'msg P2p_message.t P2p_socket.encoded_message ->
  bool Tezos_base.TzPervasives.tzresult

write_encoded_now t msg is P2p_socket.write_now t' msg where t' is the internal P2p_socket.t inside t and msg has been pre-encoded using encode. msg will be overwritten and should not be used after this invocation.

  P2p_disconnection_reason.t option

val close : 
  reason:P2p_disconnection_reason.t ->
  ('msg, 'peer, 'conn) t ->
  unit Lwt.t

val negotiated_version : 
  ('msg, 'peer, 'conn) t ->
  Tezos_base.TzPervasives.Network_version.t

Returns the network version that will be used for this connection. This network version is the best version compatible with the versions supported by ours and the remote peer.
