Struct Transaction 

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

事务包装器

使用 RAII 模式，离开作用域时自动回滚未提交的事务

Implementations

impl<'a> Transaction<'a>

pub fn begin(conn: &'a Connection) -> Result<Self, SqliteError>

开始新事务

pub fn begin_with_isolation( conn: &'a Connection, isolation: IsolationLevel, ) -> Result<Self, SqliteError>

开始事务（指定隔离级别）

pub fn begin_immediate(conn: &'a Connection) -> Result<Self, SqliteError>

开始立即事务（推荐用于写操作）

pub fn state(&self) -> TransactionState

获取事务状态

pub fn is_active(&self) -> bool

判断事务是否活跃

pub fn execute(&self, sql: &str, params: &[Param]) -> Result<usize, SqliteError>

执行 SQL

pub fn execute_batch(&self, sql: &str) -> Result<(), SqliteError>

执行批量 SQL

pub fn commit(self) -> Result<(), SqliteError>

提交事务

pub fn rollback(self) -> Result<(), SqliteError>

回滚事务

pub fn savepoint(&self, name: &str) -> Result<Savepoint<'_, 'a>, SqliteError>

创建保存点

Trait Implementations

impl<'a> Drop for Transaction<'a>

fn drop(&mut self)

Executes the destructor for this type.
