Struct mysql_async::TxOpts

pub struct TxOpts { /* fields omitted */ }

Transaction options.

Example:

let tx_opts = TxOpts::default()
    .with_consistent_snapshot(true)
    .with_isolation_level(IsolationLevel::RepeatableRead);

Implementations

impl TxOpts

pub fn new() -> TxOpts

Creates a default instance.

pub fn with_consistent_snapshot(&mut self, value: bool) -> &mut Self

See TxOpts::consistent_snapshot.

pub fn with_isolation_level<T>(&mut self, value: T) -> &mut Self where
    T: Into<Option<IsolationLevel>>, 

See TxOpts::isolation_level.

pub fn with_readonly<T>(&mut self, value: T) -> &mut Self where
    T: Into<Option<bool>>, 

See TxOpts::readonly.

pub fn consistent_snapshot(&self) -> bool

If true, then START TRANSACTION WITH CONSISTENT SNAPSHOT will be performed. Defaults to false.

pub fn isolation_level(&self) -> Option<IsolationLevel>

If not None, then SET TRANSACTION ISOLATION LEVEL .. will be performed. Defaults to None.

pub fn readonly(&self) -> Option<bool>

If not None, then SET TRANSACTION READ ONLY|WRITE will be performed. Defaults to None.

Only available since MySql 5.6.5.
