Struct RequestEnvelope 

pub struct RequestEnvelope {
    pub type_tag: String,
    pub payload: Value,
    pub request_id: Option<u64>,
    pub correlation_id: Option<String>,
}

Request envelope wrapping a message for FFI transport

The type_tag identifies the handler, and payload contains the serialized request data.

Fields

type_tag: String

Message type identifier (e.g., “user.create”, “order.submit”)

payload: Value

Serialized request payload (JSON)

request_id: Option<u64>

Optional request ID for correlation

correlation_id: Option<String>

Optional correlation ID for distributed tracing

Implementations

impl RequestEnvelope

pub fn new(type_tag: impl Into<String>, payload: Value) -> RequestEnvelope

Create a new request envelope

pub fn with_request_id(self, id: u64) -> RequestEnvelope

Set request ID

pub fn with_correlation_id(self, id: impl Into<String>) -> RequestEnvelope

Set correlation ID

pub fn from_typed<T>( type_tag: impl Into<String>, payload: &T, ) -> Result<RequestEnvelope, Error>

where T: Serialize,

Create from type tag and serializable payload

pub fn payload_as<T>(&self) -> Result<T, Error>

where T: DeserializeOwned,

Deserialize the payload to a typed value

This method deserializes directly from the JSON value without cloning.

pub fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serialize to bytes for FFI transport

pub fn from_bytes(data: &[u8]) -> Result<RequestEnvelope, Error>

Deserialize from bytes

Trait Implementations

impl Clone for RequestEnvelope

fn clone(&self) -> RequestEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RequestEnvelope

fn deserialize<__D>( __deserializer: __D, ) -> Result<RequestEnvelope, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for RequestEnvelope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
