Expand description

Trait for pluggable transaction storage backends

Implementations might be:

  • In-memory (HashMap)
  • PostgreSQL
  • Redis
  • DynamoDB
  • Any custom storage system

Required Methods§

Source

fn create<'life0, 'async_trait>( &'life0 self, record: TransactionRecord, ) -> Pin<Box<dyn Future<Output = Result<(), TransactionError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Create a new transaction

Source

fn get<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<TransactionRecord>, TransactionError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get a transaction by ID

Source

fn update<'life0, 'async_trait>( &'life0 self, record: TransactionRecord, ) -> Pin<Box<dyn Future<Output = Result<(), TransactionError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Update an existing transaction

Source

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), TransactionError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete a transaction

Source

fn list_by_user<'life0, 'life1, 'async_trait>( &'life0 self, user_id: &'life1 str, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<TransactionRecord>, TransactionError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

List transactions by user_id (for admin/debugging)

Source

fn cleanup_expired<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize, TransactionError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Cleanup expired transactions (for background job)

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
