Struct ConversationId 

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

Groups every message in one business conversation. Always derived, never minted: an un-correlated message roots its own conversation at its MessageId (see crate::EnvelopeBuilder::build), and any other value is inherited from storage or the wire via Self::from_uuid. There is deliberately no new()/Default — a random, unrooted conversation id would silently drop a caller out of the conversation it supplied (ADR 0038); a host that wants to start one names the UUID explicitly.

use reliar_core::ConversationId;
use uuid::Uuid;

// Wrap an id read back from storage or the wire without inspecting its version.
let existing = Uuid::now_v7();
let conversation = ConversationId::from_uuid(existing);
assert_eq!(conversation.as_uuid(), existing);
assert!(!conversation.is_unset());

Implementations

impl ConversationId

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);

impl ConversationId

pub const UNSET: Self

The reserved “not yet rooted” sentinel: the nil UUID. CorrelationMetadata’s default uses it, and EnvelopeBuilder::build replaces it with the envelope’s own id — conversation rooting is decided by this value, not by which builder setter was called. Self::from_uuid of any non-nil UUIDv7 is therefore never UNSET. An application SHALL NOT use the nil UUID as a real conversation id.

use reliar_core::ConversationId;
use uuid::Uuid;

assert!(ConversationId::UNSET.is_unset());
assert!(!ConversationId::from_uuid(Uuid::now_v7()).is_unset());

pub const fn is_unset(&self) -> bool

true when this id is Self::UNSET.

use reliar_core::ConversationId;
use uuid::Uuid;

assert!(ConversationId::UNSET.is_unset());
assert!(!ConversationId::from_uuid(Uuid::now_v7()).is_unset());
