Common transaction context properties.

Required Methods

fn id(&self) -> &TxnId

The TxnId of this transaction context.

fn context(&self) -> &DirLock<FE>

Allows locking the filesystem directory of this transaction context, e.g. to cache un-committed state or to compute an intermediate result.

fn subcontext<'life0, 'async_trait>( &'life0 self, id: Id ) -> Pin<Box<dyn Future<Output = TCResult<Self>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Create a new transaction context with the given id.

fn subcontext_unique<'life0, 'async_trait>( &'life0 self ) -> Pin<Box<dyn Future<Output = TCResult<Self>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Create a new transaction subcontext with its own unique [Dir].
