18 | | //! State machine of all networking connections. |
19 | | //! |
20 | | //! The [`ChainNetwork`] struct is a state machine containing multiple collections that are |
21 | | //! controlled by the API user: |
22 | | //! |
23 | | //! - A list of networking connections, identified by a [`ConnectionId`]. Each connection is |
24 | | //! either in the handshake phase, healthy, or shutting down. Each connection in the handshake |
25 | | //! phase has an optional expected [`PeerId`] representing the identity of the node that is |
26 | | //! expected to be reached once the handshake is finished. Each connection that is healthy or |
27 | | //! shutting down has an (actual) [`PeerId`] associated to it. |
28 | | //! - A list of chains, identified by a [`ChainId`]. |
29 | | //! - A set of "desired" `(ChainId, PeerId, GossipKind)` tuples representing, for each chain, the |
30 | | //! identities of the nodes that the API user wants to establish a gossip link with. |
31 | | //! |
32 | | //! In addition to this, the [`ChainNetwork`] also exposes: |
33 | | //! |
34 | | //! - A set of `(ChainId, PeerId, GossipKind)` tuples representing the gossip links that have been |
35 | | //! established. |
36 | | //! - A list of outgoing requests, identified by a [`SubstreamId`], that have been sent to a peer |
37 | | //! and that are awaiting a response. |
38 | | //! - A list of ingoing requests, identified by a [`SubstreamId`], that have been received from a |
39 | | //! peer and that must be answered by the API user. |
40 | | //! - A list of outgoing gossip link connection attempts, identified by a [`SubstreamId`], that |
41 | | //! must be answered by the peer. |
42 | | //! - A set of `(ChainId, PeerId, GossipKind)` tuples representing the peers that would like to |
43 | | //! establish a gossip link with the local node, and that are awaiting a response by the API user. |
44 | | //! |
45 | | //! # Usage |
46 | | //! |
47 | | //! At initialization, create a new [`ChainNetwork`] with [`ChainNetwork::new`], and add chains |
48 | | //! using [`ChainNetwork::add_chain`]. |
49 | | //! |
50 | | //! The [`ChainNetwork`] doesn't automatically open connections to peers. This must be done |
51 | | //! manually using [`ChainNetwork::add_single_stream_connection`] or |
52 | | //! [`ChainNetwork::add_multi_stream_connection`]. Choosing which peer to connect to and through |
53 | | //! which address is outside of the scope of this module. |
54 | | //! |
55 | | //! Adding a connection using [`ChainNetwork::add_single_stream_connection`] or |
56 | | //! [`ChainNetwork::add_multi_stream_connection`] returns a "connection task". This connection task |
57 | | //! must be processed. TODO: expand explanation here |
58 | | //! |
59 | | //! After a message has been injected using [`ChainNetwork::inject_connection_message`], repeatedly |
60 | | //! [`ChainNetwork::next_event`] until it returns `None` in order to determine what has happened. |
61 | | //! |
62 | | //! Once a connection has been established (which is indicated by a [`Event::HandshakeFinished`] |
63 | | //! event), one can open a gossip link to this peer using [`ChainNetwork::gossip_open`]. |
64 | | //! |
65 | | //! In order to faciliate this process, the [`ChainNetwork`] provides a "desired gossip links" |
66 | | //! system. Use [`ChainNetwork::gossip_insert_desired`] and [`ChainNetwork::gossip_remove_desired`] |
67 | | //! to insert or remove `(ChainId, PeerId, GossipKind)` tuples into the state machine. You can |
68 | | //! then use [`ChainNetwork::unconnected_desired`] to obtain a list of [`PeerId`]s that are marked |
69 | | //! as desired and for which a connection should be opened, and |
70 | | //! [`ChainNetwork::connected_unopened_gossip_desired`] to obtain a list of [`PeerId`]s that are |
71 | | //! marked as desired and that have a healthy connection and for which a gossip link should be |
72 | | //! opened. Marking peers as desired only influences the return values of |
73 | | //! [`ChainNetwork::unconnected_desired`] and [`ChainNetwork::connected_unopened_gossip_desired`] |
74 | | //! and has no other effect. |
75 | | //! |
76 | | |
77 | | // TODO: expand explanations once the API is finalized |
