Struct PreparedCommit 

pub struct PreparedCommit<'a> { /* private fields */ }

A transaction that has been validated and is ready to commit.

Created by Session::prepare_commit. The mutable borrow on the session prevents any concurrent operations while the commit is pending.

If dropped without calling commit or abort, the transaction is automatically rolled back.

Implementations

impl<'a> PreparedCommit<'a>

pub fn info(&self) -> &CommitInfo

Returns the commit info (mutation summary).

pub fn set_metadata(&mut self, key: impl Into<String>, value: impl Into<String>)

Attaches metadata to this commit.

Metadata is available for logging, auditing, or CDC consumers.

pub fn metadata(&self) -> &HashMap<String, String>

Returns the attached metadata.

pub fn commit(self) -> Result<EpochId>

Finalizes the commit, persisting all changes.

Consumes self to prevent double-commit.

Errors

Returns an error if the commit fails (write-write conflict, SSI violation, etc.).

pub fn abort(self) -> Result<()>

Explicitly aborts the transaction, discarding all changes.

Errors

Returns an error if the rollback fails.

Trait Implementations

impl Drop for PreparedCommit<'_>

fn drop(&mut self)
