Struct CorrelationId 

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

Groups all events and commands that originate from the same root operation.

Implementations

impl CorrelationId

pub fn new() -> Self

Generate a fresh random identifier.

pub fn from_uuid(u: Uuid) -> Self

Wrap an existing UUID.

pub fn as_uuid(self) -> Uuid

Return the underlying UUID.

impl CorrelationId

pub fn from_interchange_ref(interchange_ref: &str) -> Self

Derive a deterministic CorrelationId from an EDIFACT interchange reference string using UUID v5 (SHA-1 hash in a fixed namespace).

EDIFACT interchanges carry a reference number in UNB+…+…+<ref>. Messages retransmitted with the same reference must produce the same CorrelationId so duplicate EDIFACT messages are correlated correctly in traces and never generate spurious new process roots.

The namespace UUID is fixed and private to this crate: a3c7e1f0-5b2d-4e80-9f6a-1b3c5d7e9a0b (registered once).

Example

use mako_engine::ids::CorrelationId;

let id = CorrelationId::from_interchange_ref("A000123");
// Same reference → same CorrelationId (idempotent dispatch).
assert_eq!(id, CorrelationId::from_interchange_ref("A000123"));
// Different reference → different CorrelationId.
assert_ne!(id, CorrelationId::from_interchange_ref("A000124"));

Trait Implementations

impl Clone for CorrelationId

fn clone(&self) -> CorrelationId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CorrelationId

impl Debug for CorrelationId

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

Formats the value using the given formatter.

impl Default for CorrelationId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CorrelationId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CorrelationId

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

Formats the value using the given formatter.

impl Eq for CorrelationId

impl From<CorrelationId> for CausationId

fn from(id: CorrelationId) -> Self

Treat a correlation root as the direct cause (useful for first events).

impl From<Uuid> for CorrelationId

fn from(u: Uuid) -> Self

Converts to this type from the input type.

impl Hash for CorrelationId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CorrelationId

fn cmp(&self, other: &CorrelationId) -> 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.

impl PartialEq for CorrelationId

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CorrelationId

fn partial_cmp(&self, other: &CorrelationId) -> 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.

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

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

impl Serialize for CorrelationId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
