Struct Signed 

pub struct Signed {
    pub body: Value,
    pub sig: String,
}

A signed message: a JSON body and the Ed25519 signature over its canonical bytes under the message’s domain. The body stays JSON so that fields a newer peer adds survive verification here unchanged.

Keeping the body as JSON rather than as the bytes that were signed is what makes the protocol extensible: a field a newer peer added is carried through verification untouched, because the signature is checked over the canonical form of whatever is there rather than over a shape this version knows.

use majordomus_cli::mesh::identity::NodeIdentity;
use majordomus_cli::mesh::link::{sign, verify_signed, Domain, Signed};

let node = NodeIdentity::ephemeral().unwrap();
let signed: Signed = sign(&node, Domain::SyncRequest, serde_json::json!({ "b": 2, "a": 1 }));
assert_eq!(signed.sig.len(), 128, "hex Ed25519");

// key order is not content, so a round trip through JSON still verifies
let wire = serde_json::to_string(&signed).unwrap();
let back: Signed = serde_json::from_str(&wire).unwrap();
assert!(verify_signed(&node.public.public_key, Domain::SyncRequest, &back));

Fields

body: Value

The message.

sig: String

Hex Ed25519 over the domain and the canonical JSON of body.

Trait Implementations

impl BenchmarkCases for Signed

fn benchmark_cases(_: &CaseContext<'_>) -> Vec<NamedCase<Self>>

The cases, in a stable order. An empty list means “nothing to benchmark in this repository”, which the coverage check reports as missing.

fn benchmark_cases_json(ctx: &CaseContext<'_>) -> Vec<NamedCase<Value>>

The cases as JSON, the shape every runner serialises from.

impl Clone for Signed

fn clone(&self) -> Signed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signed

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signed

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Signed

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 Signed

fn eq(&self, other: &Signed) -> 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 Signed

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
