Enum Persistence 

pub enum Persistence {
    Permanent,
    Temporary,
}

Possible persistence levels for database objects.

This enum controls whether a table is permanent (persisted to disk) or temporary (only available in the current session).

Variants

Permanent

Permanent: The table is persisted to disk and survives session restarts.

Temporary

Temporary: The table only exists for the current session and is not persisted.

Trait Implementations

impl Clone for Persistence

fn clone(&self) -> Persistence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Persistence

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

Formats the value using the given formatter.

impl Default for Persistence

fn default() -> Persistence

Returns the “default value” for a type.

impl Display for Persistence

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

Formats the value using the given formatter.

impl PartialEq for Persistence

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

impl Copy for Persistence

impl Eq for Persistence

impl StructuralPartialEq for Persistence
