Struct Advertisement 

pub struct Advertisement {
    pub v: u32,
    pub pk: String,
    pub inst: InstanceId,
    pub name: String,
    pub seq: u64,
    pub ts: u64,
    pub ep: Vec<String>,
    pub caps: Vec<String>,
    pub repos: Vec<String>,
    pub ver: String,
    pub rt: String,
}

The advertised body: everything the signature covers. Field names are one or two characters because this travels in a single UDP datagram; the types above the wire spell things out.

Fields

v: u32

Protocol version.

pk: String

The Ed25519 public key, hex. The node id is derived from it, never carried: a field that could disagree with the key is a field somebody will forge.

inst: InstanceId

This run of the node.

name: String

A human name for the node. Presentation only.

seq: u64

Monotonic per instance: a replayed datagram carries a counter the reader has already seen and is dropped.

ts: u64

Seconds since the Unix epoch at signing time.

ep: Vec<String>

Where this node answers HTTP, as host:port authorities, at most MAX_ENDPOINTS. Advisory: an endpoint is where to try, identity is the key.

caps: Vec<String>

The transports the node serves: http, mcp, ws. Sanitized capability awareness, never an authorization.

repos: Vec<String>

The repositories this node serves, as mesh repository ids (32 hex, see super::repository): derived from the repository’s root commits or its declared identity, never from a path, so that one repository cloned on two machines is recognised as one. A digest discloses nothing; a reader that serves the same repository recognises it, anyone else learns only “some repo”.

ver: String

The executable version, informational.

rt: String

The runtime slot (16 hex): which server of this node — one per checkout. Empty in version 1. Omitted from the signed bytes when empty, so a version-1 signature verifies unchanged.

Implementations

impl Advertisement

pub fn signing_bytes(&self) -> Vec<u8>

The bytes the signature covers: the canonical JSON of the advertisement alone. Field order is the struct’s, which serde keeps stable, so signer and verifier serialize identically without a second canonicalization scheme.

pub fn node_id(&self) -> Option<NodeId>

The node id this advertisement proves, when its key parses.

Trait Implementations

impl Clone for Advertisement

fn clone(&self) -> Advertisement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Advertisement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Advertisement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Advertisement

impl JsonSchema for Advertisement

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 PartialEq for Advertisement

fn eq(&self, other: &Advertisement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Advertisement

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
