Base database writer

Quote advisory locks coordinate transactional quote updates. Callers must acquire all quote locks before taking row locks, and implementations must acquire a batch in stable order. Locks are held until the transaction commits or rolls back.

Provided Methods

fn lock_quotes<'life0, 'life1, 'async_trait>( &'life0 mut self, _quote_ids: &'life1 [QuoteId], ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Lock a set of quote identifiers for this transaction.

Returns true when the backend acquired a cross-process lock. Backends without quote advisory locks return false.

Dyn Compatibility

This trait is dyn compatible.

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