Source
pub enum Transaction {
    Start {
        isolation: Option<IsolationLevel>,
        read_only: bool,
    },
    Commit,
    Rollback,
    Savepoint(String),
    ReleaseSavepoint(String),
    RollbackToSavepoint(String),
}

Variants§

§

Start

Start a transaction with optional configuration.

When isolation is None and read_only is false, the database’s default isolation level and read-write mode are used.

Fields

§read_only: bool
§

Commit

Commit a transaction

§

Rollback

Rollback a transaction

§

Savepoint(String)

Create a savepoint with the given identifier

§

ReleaseSavepoint(String)

Release (commit) a savepoint

§

RollbackToSavepoint(String)

Rollback to a savepoint, undoing work since it was created
