One peer as every surface shows it: who it is, how this runtime reaches it, and what the link has been through. The counters are carried per peer rather than only in the totals because the question a person asks of a flapping mesh is which peer is flapping, and restarts answers a different one from reconnects — a peer whose process keeps dying, against a link that keeps dropping under a process that never did.

a.dial(&["b:1".into()]).unwrap();

let peer: &PeerView = &a.peers()[0];
assert_eq!(peer.runtime, b.runtime_key(), "the durable identity, not the endpoint");
assert!(peer.outbound, "this runtime dials it");
assert_eq!(peer.handshakes, 1);
assert_eq!(peer.restarts, 0, "the peer's process has not died under the link");

Fields

runtime: String

<node>-<runtime>: the peer’s durable identity.

node: String

The node (machine key digest).

instance: String

The current instance.

name: String

The node’s display name.

version: String

The executable version.

local: bool

Whether the peer runs on this machine (the same node key).

trust: TrustState

The trust verdict the link was admitted under.

protocol: u32

The negotiated link protocol.

features: Vec<String>

The link features the peer carries.

endpoints: Vec<String>

Where the peer answers.

state: LinkState

The link’s standing.

outbound: bool

Whether this runtime dials the peer.

inbound: bool

Whether the peer dials this runtime.

endpoint: Option<String>

The endpoint this runtime dials, when it does.

last_exchange_ms: Option<u64>

Milliseconds since the last successful exchange in either direction.

rtt_ms: Option<u64>

The last round trip, milliseconds.

failures: u32

Consecutive failed rounds.

last_error: Option<String>

The last failure, in words.

handshakes: u64

Handshakes completed with this peer.

reconnects: u64

Handshakes after an expiry or a dropped link.

restarts: u64

New instances of the peer seen (its process restarted).

linked_at: String

When the current link was established, RFC 3339.

Trait Implementations

impl Clone for PeerView

fn clone(&self) -> PeerView

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PeerView

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PeerView

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PeerView

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for PeerView

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
