Enum DbTransaction 

pub enum DbTransaction {
    Sqlite(Transaction<'static, Sqlite>),
    Postgres(Transaction<'static, Postgres>),
    MySql(Transaction<'static, MySql>),
}

Available on crate features model-mysql or model-postgres or model-sqlite only.

An in-progress database transaction.

Created with DbPool::begin. Calling commit commits the transaction; dropping without committing rolls it back.

Variants

Sqlite(Transaction<'static, Sqlite>)

Available on crate feature model-sqlite only.

Postgres(Transaction<'static, Postgres>)

Available on crate feature model-postgres only.

MySql(Transaction<'static, MySql>)

Available on crate feature model-mysql only.

Implementations

impl DbTransaction

pub async fn execute( &mut self, sql: &str, params: &[Value], ) -> Result<u64, DbError>

Execute a SQL statement inside this transaction.

pub async fn query_rows( &mut self, sql: &str, params: &[Value], ) -> Result<Vec<ModelRow>, DbError>

Execute a SQL query inside this transaction, returning untyped rows.

pub async fn query<T: Model>( &mut self, sql: &str, params: &[Value], ) -> Result<Vec<T>, DbError>

Execute a SQL query inside this transaction and deserialise into T: Model.

pub async fn commit(self) -> Result<(), DbError>

Commit this transaction.

pub async fn rollback(self) -> Result<(), DbError>

Roll back this transaction explicitly (also happens on drop).
