Record version isolation

Variants

RecordVersion

Is a kind of two-phase locking mechanism: it will make the transaction unable to write to any row that has an update pending from another transaction

NoRecordVersion

The transaction reads the latest committed version of the row, regardless of other pending versions of the row.

Trait Implementations

impl Clone for TrRecordVersion

fn clone(&self) -> TrRecordVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TrRecordVersion

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

Formats the value using the given formatter.

impl Default for TrRecordVersion

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<TrRecordVersion> for TrRecordVersion

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

This method tests for self and other values to be equal, and is used by ==.

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

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