Struct nebari::transaction::ManagedTransaction

source · [−]

pub struct ManagedTransaction<Manager: FileManager> { /* private fields */ }

Expand description

A transaction that is managed by a TransactionManager.

Implementations

source

impl<Manager: FileManager> ManagedTransaction<Manager>

source

pub fn commit(self) -> Result<TreeLocks, Error>

Commits the transaction to the transaction manager that created this transaction.

source

pub fn rollback(self)

Rolls the transaction back. It is not necessary to call this function – transactions will automatically be rolled back when the handle is dropped, if commit() isn’t called first.

Methods from Deref<Target = LogEntry<'static>>

source

pub fn data(&self) -> Option<&ArcBytes<'a>>

Returns the associated data, if any.

source

pub fn set_data(&mut self, data: impl Into<ArcBytes<'a>>) -> Result<(), Error>

Sets the associated data that will be stored in the transaction log. Limited to a length 16,777,208 (2^24 - 8) bytes – just shy of 16MB.
