Struct SessionMessageEnvelope 

pub struct SessionMessageEnvelope {
    pub id: SessionMessageId,
    pub source: SessionMessageSource,
    pub target_session_id: String,
    pub kind: SessionMessageKind,
    pub body: SessionMessageBody,
    pub created_at: DateTime<Utc>,
    pub thread_id: Option<String>,
    pub in_reply_to: Option<SessionMessageId>,
    pub attempt: Option<u32>,
    pub correlation_id: Option<String>,
}

Stable, dependency-light envelope persisted in each logical session inbox.

Fields

id: SessionMessageId

source: SessionMessageSource

target_session_id: String

kind: SessionMessageKind

body: SessionMessageBody

created_at: DateTime<Utc>

thread_id: Option<String>

in_reply_to: Option<SessionMessageId>

attempt: Option<u32>

correlation_id: Option<String>

Implementations

impl SessionMessageEnvelope

pub fn user_input( target_session_id: impl Into<String>, text: impl Into<String>, ) -> SessionMessageEnvelope

pub fn validate(&self) -> Result<(), SessionMessageValidationError>

pub fn idempotency_semantics(&self) -> Value

Canonical fields that define one logical delivery for idempotency and transcript-proof purposes. Transport/retry metadata (created_at and attempt) is deliberately excluded. Provider presentation is derived by trusted runtime producers and is also excluded: the first durable envelope wins presentation for an otherwise identical typed outcome.

pub fn to_provider_message( &self, ) -> Result<Message, SessionMessageValidationError>

Translate the delivery envelope to a replayable provider-valid user message while retaining all correlation metadata.
