Struct RequestId 

pub struct RequestId(/* private fields */);

Correlates an envelope back to the inbound request (HTTP call, RPC, CLI invocation) that caused it, so an outbound message can be traced to its trigger. Always host-supplied: there is deliberately no new()/Default, since a minted request id would claim an inbound request exists when none does (ADR 0038). A host wraps the id it already has with Self::from_uuid.

use reliar_core::RequestId;
use uuid::Uuid;

// Wrap the inbound request's own id — never minted.
let inbound = Uuid::now_v7();
let request_id = RequestId::from_uuid(inbound);
assert_eq!(request_id, RequestId::from_uuid(request_id.as_uuid()));

Implementations

impl RequestId

pub const fn from_uuid(id: Uuid) -> Self

Wraps an existing UUID without inspecting or rejecting its version.

// Illustrative for every id type this macro declares.
use reliar_core::MessageId;
use uuid::Uuid;

let raw = Uuid::now_v7();
assert_eq!(MessageId::from_uuid(raw).as_uuid(), raw);

pub const fn as_uuid(&self) -> Uuid

Returns the inner UUID.

// Illustrative for every id type this macro declares.
use reliar_core::MessageId;
use uuid::Uuid;

let raw = Uuid::now_v7();
assert_eq!(MessageId::from_uuid(raw).as_uuid(), raw);
