Struct EventId 

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

Value Object: EventId

Represents a unique identifier for an event in the event store.

Domain Rules:

• Must be a valid UUID
• Immutable once created
• Globally unique within the event store

This is a Value Object:

• Defined by its value, not identity
• Immutable
• Self-validating
• Compared by value equality

Implementations

impl EventId

pub fn new() -> Self

Create a new EventId with a random UUID

Examples

use allsource_core::domain::value_objects::EventId;

let event_id = EventId::new();
assert!(!event_id.is_nil());

pub fn from_uuid(uuid: Uuid) -> Self

Create an EventId from an existing UUID

Examples

use allsource_core::domain::value_objects::EventId;
use uuid::Uuid;

let uuid = Uuid::new_v4();
let event_id = EventId::from_uuid(uuid);
assert_eq!(event_id.as_uuid(), uuid);

pub fn parse(value: &str) -> Result<Self>

Parse an EventId from a string

Errors

Returns error if the string is not a valid UUID

Examples

use allsource_core::domain::value_objects::EventId;

let event_id = EventId::parse("550e8400-e29b-41d4-a716-446655440000").unwrap();
assert_eq!(event_id.to_string(), "550e8400-e29b-41d4-a716-446655440000");

pub fn as_uuid(&self) -> Uuid

Get the UUID value

pub fn is_nil(&self) -> bool

Check if this is a nil (all zeros) UUID

pub fn nil() -> Self

Create a nil EventId (for testing or placeholders)

Trait Implementations

impl AsRef<Uuid> for EventId

fn as_ref(&self) -> &Uuid

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for EventId

fn clone(&self) -> EventId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventId

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

Formats the value using the given formatter.

impl Default for EventId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EventId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EventId

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

Formats the value using the given formatter.

impl From<EventId> for Uuid

fn from(event_id: EventId) -> Self

Converts to this type from the input type.

impl From<Uuid> for EventId

fn from(uuid: Uuid) -> Self

Converts to this type from the input type.

impl Hash for EventId

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 PartialEq for EventId

fn eq(&self, other: &EventId) -> 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 Serialize for EventId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for EventId

type Error = AllSourceError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self>

Performs the conversion.

impl TryFrom<String> for EventId

type Error = AllSourceError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self>

Performs the conversion.

impl Copy for EventId

impl Eq for EventId

impl StructuralPartialEq for EventId
