Enum IsolationLevel 

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

Transaction isolation levels

Variants

ReadUncommitted

Read uncommitted - dirty reads possible

ReadCommitted

Read committed - no dirty reads (PostgreSQL default)

RepeatableRead

Repeatable read - no non-repeatable reads (MySQL default)

Serializable

Serializable - full isolation

Snapshot

Snapshot isolation (SQL Server specific)

Implementations

impl IsolationLevel

pub fn to_sql(&self) -> &'static str

Convert to SQL string for SET TRANSACTION statement

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 Display for IsolationLevel

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

Formats the value using the given formatter.

impl Hash for IsolationLevel

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 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.
