Struct ConversationId 

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

Groups every message in one business conversation. Defaults to the id of the message that starts it (see crate::EnvelopeBuilder::build), so an un-correlated message is the root of its own conversation.

Implementations

impl ConversationId

pub fn new() -> Self

Generates a fresh UUIDv7 id.

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

Wraps an existing UUID without inspecting or rejecting its version.

pub const fn as_uuid(&self) -> Uuid

Returns the inner UUID.

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::new/Self::default mint a fresh UUIDv7 and are therefore never UNSET. An application SHALL NOT use the nil UUID as a real conversation id.

pub const fn is_unset(&self) -> bool

true when this id is Self::UNSET.

impl Ord for ConversationId

fn cmp(&self, other: &ConversationId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ConversationId

fn eq(&self, other: &ConversationId) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for ConversationId

fn partial_cmp(&self, other: &ConversationId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.
