Enum IsolationLevel 

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

Transaction isolation levels.

Variants

ReadUncommitted

Read uncommitted - allows dirty reads.

ReadCommitted

Read committed - prevents dirty reads.

RepeatableRead

Repeatable read - prevents non-repeatable reads.

Serializable

Serializable - highest isolation level.

Implementations

impl IsolationLevel

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

Get the SQL clause for this isolation level.

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 Default for IsolationLevel

fn default() -> IsolationLevel

Returns the “default value” for a type.

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.
