Struct Envelope 

pub struct Envelope {
    pub v: u8,
    pub payload: String,
    pub nonce: String,
    pub ts: i64,
    pub sig: Option<Sig>,
}

A versioned, signed (or freshness-stamped) message envelope (ADR-020 §3).

payload/nonce/the signature are carried base64-encoded so the envelope is JSON/transport-friendly and transport-agnostic (a consumer applies it to HTTP bodies, its own UDP gossip, anything). In Open posture sig is absent.

Fields

v: u8

Wire version — selects the verification construction (see ENVELOPE_V1).

payload: String

The signed bytes, base64 (standard) encoded.

nonce: String

A random per-message nonce, base64 (standard) encoded — replay uniqueness.

ts: i64

Signer’s clock at sign time, unix seconds — drives the freshness window.

sig: Option<Sig>

The signature block. Absent in Open posture (a freshness-stamped passthrough); present and verified in Authenticated posture.

Trait Implementations

impl Clone for Envelope

fn clone(&self) -> Envelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposeSchema for Envelope

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for Envelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Envelope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Envelope

impl PartialEq for Envelope

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Envelope

impl ToSchema for Envelope

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

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference utoipa::openapi::schema::Schemas for this type.
