Enum IsolationLevel 

pub enum IsolationLevel {
    ReadUncommitted,
    ReadCommitted,
    RepeatableRead,
    Serializable,
}

SQL transaction isolation levels.

Not all backends support all levels. The driver returns an error if an unsupported level is requested.

Examples

use toasty_core::driver::operation::IsolationLevel;

let level = IsolationLevel::Serializable;
assert_eq!(level, IsolationLevel::Serializable);

Variants

ReadUncommitted

Transactions can see uncommitted changes from other transactions.

ReadCommitted

Transactions only see changes committed before each statement.

RepeatableRead

Transactions see a consistent snapshot from the start of the transaction.

Serializable

Full serializability; transactions behave as if executed one at a time.

Trait Implementations

impl Clone for IsolationLevel

fn clone(&self) -> IsolationLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IsolationLevel

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

Formats the value using the given formatter.

impl PartialEq for IsolationLevel

fn eq(&self, other: &IsolationLevel) -> 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.
