event-store-adapter-rs

This library is designed to turn DynamoDB into an Event Store for Event Sourcing.

Usage

You can easily implement an Event Sourcing-enabled repository using EventStore.

```rust pub struct UserAccountRepository { event_store: EventStore, }

impl UserAccountRepository { pub fn new(eventstore: EventStore) -> Self { Self { eventstore } }

pub async fn store( &mut self, event: &UserAccountEvent, version: usize, snapshotopt: Option<&UserAccount>, ) -> Result<()> { self .eventstore .storeeventwithsnapshotopt(event, version, snapshot_opt) .await }

pub async fn findbyid(&self, id: &UserAccountId) -> Result { let (snapshot, seqnr, version) = self.eventstore.getsnapshotbyid(id).await?; let events = self.eventstore.geteventsbyidandseqnr(id, seq_nr).await?; let result = UserAccount::replay(events, Some(snapshot), version); Ok(result) } } ```
