Struct TxOpts

pub struct TxOpts { /* private fields */ }

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.

Trait Implementations

impl Clone for TxOpts

fn clone(&self) -> TxOpts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TxOpts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TxOpts

fn default() -> TxOpts

Returns the “default value” for a type.

impl Hash for TxOpts

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TxOpts

fn eq(&self, other: &TxOpts) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
