    RepeatableRead,
    ReadCommitted,
    ReadUncommitted,
    Serializable,
}

Isolation level

Variants

RepeatableRead

Consistent reads within the same transaction read the snapshot established by the first read.

ReadCommitted

Each consistent read, even within the same transaction, sets and reads its own fresh snapshot.

ReadUncommitted

SELECT statements are performed in a nonlocking fashion, but a possible earlier version of a row might be used.

Serializable

All statements of the current transaction can only see rows committed before the first query or data-modification statement was executed in this transaction.

Trait Implementations

impl Clone for IsolationLevel

fn clone(&self) -> IsolationLevel

Returns a copy 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 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.
