Struct UuidV7Generator 

pub struct UuidV7Generator<Id>(/* private fields */);

Generates ids from a time-ordered (v7) UUID.

Examples

use ddd_toolkit_core::adapter::id::UuidV7Generator;
use ddd_toolkit_core::domain::{EntityId, ValueObject};
use ddd_toolkit_core::port::id::IdGenerator;
use std::convert::Infallible;
use std::fmt::Display;

#[derive(Debug, Clone, PartialEq, Eq, Hash, PartialOrd, Ord)]
struct OrderId(uuid::Uuid);

impl ValueObject for OrderId {}

impl Display for OrderId {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        write!(f, "{}", self.0)
    }
}

impl EntityId for OrderId {}

impl TryFrom<uuid::Uuid> for OrderId {
    type Error = Infallible;
    fn try_from(value: uuid::Uuid) -> Result<Self, Self::Error> {
        Ok(Self(value))
    }
}

let generator = UuidV7Generator::<OrderId>::new();

// v7 ids are time-ordered, so ids minted later sort after earlier ones
let first = generator.generate();
let second = generator.generate();
assert!(first <= second);
